The following is a detailed list of Bolo tanks, from the fictional Bolo series by Keith Laumer.

Manned Bolos

Mark I Bolo

The Mark I Bolo was introduced in 2000 as a comprehensive upgrade of the Abrams. The Mark I mounted a 150mm cannon which fired discarding sabot, fin-stabilized, long-rod penetrator (DSFSLRP) rounds, allowing it to defeat the Chobham armor used on other MTBs of the time. The Mark I was also fitted with computer controlled anti-personnel/point defense gatlings with integral radar, probably similar to the Phalanx CIWS. The Mark I required a crew of four, was powered by two fossil-fuel power plants, and weighed in at 150 metric tons. Despite the greatly increased weight, the Mark I had a road speed of 80 km/h and combat radius of 1000km.

Mark II Bolo

The Mark II Bolo was an updated Mark I first released in 2015. It required only a single crew member due to heavy automation and improved computer controls. The Mark II supplemented the Mark I's CIWS with two railguns on each flank. These railguns were dubbed infinite repeaters, a name that would be adopted to cover all Bolo secondary guns in the coming models. The Mark II was also the first Bolo to be armored with 10mm of durachrome which greatly increased its survivability compared to the Mark I, rendering it immune to anything less than its own 150mm DSFSLRP. The Mark II used two fossil-fuel power plants, but these charged a generator and ionic batteries instead of directly connecting to the drive train. Without fuel the batteries could provide 12 hours of power, and could be recharged from a civilian power grid. The Mark II's improvements increased its weight to 194 metric tons, but it retains a road speed of 80 km/h with an off-road speed of 30 km/h. The Mark II was the last Bolo to use only two treads.

Mark III Bolo

The Mark III Bolo entered service in 2018, not to replace the Mark II, but to supplement it in a heavy support roll. The Mark III's 150mm cannon has only a 20 degree fire arc to the front, but it mounted four 155mm howitzers, a Vertical Launching System and eight railgun infinite repeaters. The Mark III was armored with 20mm of Durachrome which, short of a hit from the Bolo's own 150mm DSFSLRP at under 250m, required a contact nuclear detonation to breach. The Mark III used only one fossil-fuel power plant, relying instead on using solar film to recharge its batteries. The Mark III was given an improved sensor suite and an electronics officer was added for a total of two crew members, although with automation it could still be run by a single man. The Mark III ran on 4 treads, with the inner and outer pair having separate drive systems. However due to its weight of 300 metric tons the Mark III had a road speed of 50 km/h and an off-road speed of 25 km/h.

Mark IV Bolo

The Mark IV Bolo was introduced in 2116, making it the first post-collapse Bolo. The Mark IV's main armament was a 165mm railgun, backed by a VLS containing 75 cells with both indirect fire and SAM capabilities. The Mark IV's CIWS consisted of six 20mm infinite repeater railguns supplemented by laser clusters, making it the first Bolo to mount energy weapons. The Mark IV used the same power plant as the Mark III, but with improved solar film so that it could recharge on the move. The Mark IV was armored with 30mm of durachrome. The Model B (the first model as GM decided that the designation Model A had been permanently preempted by Ford) weighed in at 210 metric tons, and had a road speed of 60 km/h and an off-road speed of 30 km/h. Subsequent models added sensors and additional VLS cells, and so by the end of the Mark IV's operation life the Model H weighed 340 metric tons and had a road speed dropped to 40 km/h, with very little off-road capability.

Mark V Bolo

The Mark V was introduced in 2160 and was the first model of Bolo capable of deep wading, that is crossing water obstacles without assistance, by buttoning up and driving across the bottom. The Mark V also demanded more power than solar recharging and batteries could supply and so it was fitted with an internal fission plant. The Mark V mounted a 190mm railgun and twelve 60mm gating infinite repeaters (six per side) that fired depleted uranium rounds as well as lighter gatlings and laser clusters for point defense. Flechette and HE launchers supplemented the lasers for anti-personnel work and would become standard on every proceeding Bolo. The Mark V had a reduced missile compliment, restricting it to only SAMs. The Mark V weighed 198 metric tons with a road speed of 80 km/h and an off-road speed of 50 km/h, and was crewed by a single operator.

Mark VI Bolo

The Mark VI entered service in 2162 and like the Mark III was designed as a supplementary heavy support unit. The Mark VI had no main gun, instead relying on missile batteries, although it increased the count of 60mm gatlings to seven on each side, and mounted a larger CWIS system to support surrounding units and act in a counter battery roll. Like the Mark V the Mark VI had a one man crew, a road speed of 80 km/h and an off-road speed of 50 km/h, although its weight increased to 238 metric tons.

Mark VII Bolo

The Mark VII rolled off the production lines in 2163 and was designed as a heavier counterpart of the Mark V and Mark VII. Its main armament consisted of a 200mm railgun which was backed by a bank of seven 75mm gatling infinite repeaters on either flank. The Mark VII carried a missile compliment that was mainly designed for bombardment, but could be tasked for anti-air duties. The Mark VII used layered durachrome with a total thickness of 120mm. The Mark VII required a crew of two, with the added man controlling the indirect fire weapons in the Model B, but later being changed to a dedicated air defense and anti-missile position. The Mark VII weighed 348 tons with a road speed of 40 km/h and an off-road speed of 30 km/h.

Mark VIII Bolo

The Mark VIII came into service in 2209. It was armed with a high velocity 170mm railgun which gave it greater punch than earlier models despite a smaller bore. The Mark VIII used twelve laser infinite repeaters which were less effective than the gatlings of earlier models, but were lighter and not dependent on a supply of ammunition. The Mark VIII's missile load was reduced compared to previous Bolos and relegated solely to SAM and point defense. However the Mark VIII was equipped four 150mm rapid fire howitzers to provide it with some indirect fire capability. The Mark VII used a fission reactor, but also had solar back up. It required a crew of one, weighed 225 metric tons and had a road speed of 65 km/h with the ability to dash at 85 km/h for short periods with reduced handling.

Mark IX Bolo

The Mark IX Bolo came out at the same time as the Mark VIII and was designed as a support vehicle. It carried no direct fire weapon instead relying on VLS and four 180mm high-trajectory howitzers in twin mountings. Improvements in electronics allowed the Mark IX to be crewed by a single individual. It weighed 400 metric tons with a road speed of 57 km/h.

Semi-Manned Bolos

Mark X Bolo

The Mark X Bolo, introduced in 2235, was the first to mount a laser cannon as its main armament. While less efficient in a transfer of energy per shot basis than previous Bolo weapons, the laser removed the need for ammunition storage in the Mark X. The Mark X used the same laser repeaters and in the same number as the Mark IX, but it upgraded the point defenses to use multibarreled, independently turreted flechette railguns. The Mark X carried only a defensive missile load, and mounted no indirect fire weaponry. It did however have a powerful computer core which allowed it to be run by a single man and in latter models allowed it to be run by pre-loaded battle plans, requiring human intervention only if it encountered something wholly unexpected. The Mark X weighed 350 metric tons, with a road speed of 70 km/h.

Mark XI Bolo

The Mark XI was introduced at the exact same time as the Mark X, and was designed as a fail safe incase the Mark X's laser cannon proved impractical. The Mark XI was identical to the Mark X, but was instead armed with a 18cm railgun capable of firing multiple projectile types including DSFSLRP, cluster munitions, chemical weapons, incendiaries and fuel-air explosives.

Mark XII Bolo

Put into service in 2240, the Mark XII was the first "continental siege unit", designed to attack targets on different continents from the one upon which the Mark XII was deployed. The Mark XII's VLS cells were capable of launching ICBMs with MIRVs, or surface-to-space missiles. The Mark XII had no main anti-armor weapon, but had effective anti-air/anti-missile systems. The Mark XII was often paired with a Bolo Ammunition Vehicle, a Mark XII hull with all armaments stripped to provide room for housing extra ammunition. The Mark XII carried a one man crew, although it was primarily designed to be run by preloaded battle plans. It weighed 500 metric tons and had a road speed of 50 km/h.

Mark XIII Bolo

The Mark XIII entered service only seven years after the Mark XII, but even in this short amount of time technology advanced enough to make the Mark XIII a far more efficient fighting machine. The Mark XIII was for all intents and purposes a Mark XII with anti-armor weapons installed. Even though the added main armament took up 25% of the weight allocated for missile batteries in the Mark XII, the Mark XIII actually had improved bombardment capabilities as advancements in fission power allowed a much smaller reactor to be installed, granting more weight for missiles. The Mark XIII also reduced weight by using flintsteel under a layer of durachrome for armor, instead of pure durachrome. The Mark XII Model B weighed in at 565 metric tons with a road speed of 50 km/h, although later models were able to increase the speed to 75 km/h through better suspension and power trains without increasing weight.

Mark XIV Bolo

The Mark XIV entered service in 2307 and saw the mounting of a weapon that would become the standard of all future Bolos: The Hellbore Plasmagun. Originally designed as the main battery armament of the Concordiat Navy's Magyar-class battlecruiser, the 25cm Hellbore delivered half a megaton per second and out preformed any laser or projectile weapon of equal mass. The Mark XIV also benefited from mag-bottle technology allowing it to use a fusion plant instead of the fission models used by earlier Bolos. Indirect bombardment capabilities were reduced to only what was necessary at the tactical level, mainly because point defense weapons of the time had become so effective that strategic bombardment had become pointless. By reducing the requirements for indirect fire, the Mark XIV was able to make use of smaller missiles allowing it to increase its missile load out compared to previous Marks of Bolo without a major increase in weight. With so much new technology added the Mark XIV weighed an impressive 728 metric tons which increased to 900 in the later models. However advancements in suspension and drive trains kept it as maneuverable and capable as the Mark XIII, and its road speed stayed between 60 and 75 km/h through all models.

Unmanned Bolos

Mark XV/B-M Bolo (Resartus)

The Mark XV first rolled off the production lines in 2396. The Mark XV was notable in that it was the first Bolo that does not require a human to operate it. Where as other Bolo could function on preset battle plans they still required a human to make decisions that were not included in the plan, but advancements in secure subspace communications and cybernetics allowed the Mark XV to self direct with any human input able to be sent remotely. The Mark XV’s cybernetics were separated into two computer cores, a primary and secondary, which were housed in separate compartments to provide redundancy. The Mark XV was armed with a 25cm Hellbore which could hit any land based target in line of sight, but was not powerful enough to engage orbital targets due to dissipation in the atmosphere. The Hellbore was backed by fourteen gatling laser infinite repeaters, in banks of seven down each flank. The Mark XV also mounted four 20cm howitzers for tactical bombardment, and in such a role it had capabilities equivalent to a Mark XIV. The Mark XV did away completely with durachrome and instead used pure flintsteel although early models continued to use anti-kinetic reactive armor, it was removed in later models, marking the last time it was used on a Bolo. Due to a large increase in weight (the Mark XV Model B weighed 1,500 metric tons which increased to over 3,000 by the Model M) the Mark XV required a new suspension system, and a separate power train for each of the six track systems powered by two fusion reactors. The Mark XV had a road speed of 65 km/h, with a short sprint speed of 80 km/h. The Mark XV also had a special Model L that weighed only 1,100 tons, and was capable of 37% higher combat speeds. It was designed as a EW model.

Mark XV/Q-R Bolo (Horrendous)

The Model R, finalized in 2626, was the last model of Mark XV to be produced. It had been up gunned to a 50cm Hellbore which unlike previous models was able to engage targets in low orbit from within an atmosphere. It also mounted ablative armor appliqués to help defend it against an increase in vehicle and infantry weapon power. The Model Q had greatly increased EW capabilities, and was the first Bolo whose cybernetics were powerful enough to compare the actually battle conditions to its preloaded battle plans and suggest improvements. With express human authorization, the Models Q and R were able to reconfigure these plans without direct human input, and so while not entirely self directing, they gave a good impression of being so. The Mark XV/R weighed 5,000 metric tons, but maintained a road speed of 65-70 km/h.

Mark XVI Bolo (Retarius)

The Mark XVI was put into service in 2650 and was designed as a light version of the Mark XVI. It maintained the 50cm Hellbore, but reduced the infinite repeaters to four on each flank. However, the infinite repeaters were upgraded from lasers to ion bolt projectors giving them increased anti-armor performance. The Mark XVI also mounted six, beech loading 20cm mortars for anti-infantry work. The ablative appliqués were replaced with an entirely ablative outer hull. The Mark XVI mounted cybernetics of the same quality as the Mark XV/R. Weighed was reduced to 3,600 metric tons and road speed rose to 90 km/h, with sprints up to 100 km/h. The Mark XVI formed the light regiments of the original Dinochrome Brigade.

Mark XVII Bolo (Implacable)

The Mark XVII was introduced in 2650 along side the Mark XVI as the heavy version of the Mark XV. The Mark XVII's main armament was upgraded to a 60cm Hellbore, and it mounted fifteen ion-bolt infinite repeaters, six on each flank and three on the glacis. The Mark XVII’s removed the mortars found on the Mark XVI and replaced them with six 25cm howitzers and an increased missile armament. The Mark XVII weighed 6,500 metric tons and had a road speed of 75 km/h. The Mark XVII formed the heavy regiments of the original Dinochrome Brigade.

Mark XVIII Bolo (Gladius)

The Mark XVIII was designed in 2672 to replace both the Mark XVI and XVII, combining the best features of both previous Bolos. The main weapon remained a 60cm Hellbore, but the ion-bolt infinite repeaters were reduced to six on each flank, as the glacis mounted ones had reduced the structural integrity of the front armor. The Mark XVIII used a three layer hull design consisting of an outer layer of ablative armor, a thin middle layer of duralloy, and a flintsteel inner layer. The Mark XVIII also mounted a third fusion plant, which combined with greater fire control, plasma containment technology, and weapon power allowed the 60cm Hellbore to engage targets in medium orbit. Later models of the Mark XVIII weighed almost 10,000 metric tons, but it maintained a speed of 70 km/h, with a sprint speed of 80 km/h. At this point, off-road and road speed were nearly the same, due to the mass of the Bolo. The Mark XVIII formed the first general purpose regiments of the Dinochrome Brigade.

Mark XIX Bolo (Intransigent)

Introduced in 2790, the Mark XIX was the first real improvement over the Mark XV, as all following Bolos had up-armored and up-gunned versions of the Mark XV. The Mark XIX was the first Bolo to make use of anti-kinetic battle screens, energy shields which acted as its first line of defense against projectiles. The battle screens were also able to convert energy weapon fire that hit it into power the Bolo could draw on. The Mark XIX was armed with a 60cm Hellbore backed by sixteen ion-bolt infinite repeaters and 35mm gatling railguns. The Mark XIX mounted eight 30cm breech-loading mortars. The Mark XIX was fitted with a "plasma-shedding" ceramic tile appliqué. The Mark XIX weighed 13,000 metric tons with a road speed of 90 km/h and a sprint speed of 120 km/h. Due the drastically increased weight of the Mark XIX a special transport was designed for it. The transport was able to deploy two Mark XIXs in almost any terrain, and was a vast improvement over previous drop pods that had been used, although pods of varying types would remain in service for 400 years.

Self-Aware Bolos

Mark XX/B Bolo (Tremendous)

Introduced in 2796, the Mark XX was the first truly self-directing self-aware Bolo, made possible by breakthroughs in psychotronics. It maintained the same defensive capabilities as the Mark XIX but was forced to down size its main armament from a single 50cm Hellbore to dual 30cm models because of the space taken up by the new psychotronics. The Mark XX weighed 13,000 metric tons with a road speed of 90 km/h and a sprint speed of 120 km/h.

Mark XX/M Bolo (Tremendous)

Nicknamed the Mosby, the Mark XX/M was designed as an independent raider that could be deployed behind enemy lines to disrupt logistics and communications. The Mark XX/M was built on refitted Mark XIV’s hulls, removing the Hellbore and its turret to make space for a psychotronic system similar to the ones included in normal Mark XX, although with reduced capability. The reduced psychotronic system created a simple personality that had the side effect of being rather blood thirsty. This personality was suppressed by software unless in a combat zone to prevent any problems.

Mark XXI Bolo (Terrible)

The Mark XXI was introduced in 2869 and marked a change in the nomenclature of Bolo Marks. Whereas previously major structural changes where given new designations, with the Mark XXI it was decided that only an increase in psychotronic ability would justify a new Mark of Bolo. The Mark XXI mounted a single 60cm Hellbore. With increases in computing power the Mark XXI was much more capable in combat although outside of combat it had the same restraint programs to prevent it from self direction. The Mark XXI introduced Total Systems Data-Sharing (TSDS) which allowed the bolos to form a distributed intelligence that controlled the actions of all bolos on the field. The Mark XXI also included a special reconnaissance variant the Mark XXI/I.

Mark XXII Bolo (Thunderous)

The Mark XXII, introduced in 2890, boasted improved cybernetics and psychotronics. The Mark XXII also mounted a 90cm Hellbore that was rated at 2 megatons/second. The Mark XXII was the first Bolo with interplanetary subspace communication capabilities, it was also the first Bolo that was allowed to control the systems on its unmanned transport aircraft, allowing it better survival during insertion. The Mark XXII also had its kinetic battle screens improved, making them 36% more effect than those of the Mark XXI. The Mark XXII weighed 14,000-15,000 tons depending on the specific model, had a top speed of 80 km/h and a sprit speed of 120-135 km/h.

Mark XXIII Bolo (Invincibilis)

The Mark XXIII entered service in 2912 in anticipation of the coming conflict with the Quern Hegemony. The Mark XXIII mounted a two 80cm Hellebores in fore and aft turrets as well as eighteen ion-bolt infinite repeaters with nine mounted on either flank. The Mark XXIII boasted slightly improved psychotronics and its battle screens were supplemented by internal disrupter shields that protected key components of the Bolo. During the war with the Quern, a breakthrough in artificial intelligence circuitry was made and so late Mark XXIIIs were outfitted with molecular circuitry which greatly increased their performance without a corresponding increase in volume. The Mark XXIII also mounted a secondary computer core, giving it greater survivability through redundancy. The Mark XXIII weighed 15,000 metric tons with its speed remaining close to that of the Mark XXII. It was able to maintain a similar weight while increasing its armament due to the weight saved by the new circuits and by switch its armor from flintsteel to a new duralloy which provided the same protection for half the weight.

Mark XXIV Bolo (Cognitus)

The Mark XXIV was put into service in 2961 and was the first truly autonomous Bolo as, with improvements in its personality center and id integration circuits, it was able to self-direct strategically as well as tactically. The Mark XXIV was the first Bolo to develop human level individuality in personality, but it retained the inhibitory programming safeguards from earlier models. However, the Mark XXIV was allowed a greater degree of freedom out side of combat than previous models. Although this Mark signaled the beginnings of the movement to completely remove these safeguards, Bolo Central still resisted and only changed its mind after reviewing the battle records from Unit 0075-NKE “Nike” from the Battle of Santa Cruz in 3025. The Mark XXIV mounted a single 90cm “super” Hellbore. Reducing the main armament did not decrease weight much, and the Mark XXIV still massed 14,000 metric tons. Its ground speed remained comparable to the Mark XXIII and Mark XXII.

Mark XXV Bolo (Stupendous)

By 3001 a general consensus was reached by Bolo Central that the inhibitory software loaded on Bolos since the Mark XX was unnecessary and actually hindered combat performance. The Model B therefore had greatly reduced restrictions, and by the Model D (introduced in 3029) virtually all inhibitory software had been removed. The Mark XXV maintained a core package of this software incase a Bolo went rogue through battle damage or poor maintenance with one of the key aspects of this package being the “Omega-Worm” which would completely destroy a rogue Bolo’s computer cores. As the restrictions on the Bolo’s AI were removed combat performance greatly increased. The Mark XXV essentially duplicated the armor and armament of the Mark XXIV, but due to improvement in metallurgy and the efficiency of its fusion plant weight was reduced to 13,000 metric tons. Normal operating speed rose to 95 km/h, but sprit speeds remained the same as previous models.

Mark XXVI Bolo (Monstrous)

The Mark XXVI entered service in 3113 and was the first Bolo to feature the “hyper-heuristics” developed by Major Marina Stavrakas. Physically the Mark XXVI was almost unchanged from the Mark XXV, although the Mark XXVI was able to construct “learning models” much more quickly. This capability granted the Mark XXVI an almost precognative ability in projecting changes in the enemy’s tactical or strategic plans, often doing so before even the enemy was aware of their own intent to change their plans. With a much greater ability to intercept and decrypt enemy communications, the Mark XXVI was frequently able to invade the enemy’s data net to search for useful information, sow deception, or even subvert the machines for its own uses.

Mark XXVII Bolo (Invictus)

The Mark XXVII was first deployed in 3185 and was, along with the Mark XXVIII and Mark XXIX, designed to operate as part of the newly formed independent Bolo brigades. The Mark XXVII was the first Bolo to replace all wiring with molecular circuitry, except for those powering weapons. The Mark XXVII mounted a single 110cm “super” Hellbore (rated at 2.75 megatons/second) but had greatly reduced secondary weapons. The Mark XXVII was designed to serve as a scouting and screening force for the heavier Mark XXVIIIs and Mark XXIXs that made up the rest of the Bolo brigades, a role that had formally been preformed by lighter vehicles, either manned or unmanned, or even Mark XXI/Is with upgraded psychotronics. The Mark XXVII had the advantage that it was much more combat worthy then these other vehicles and was able to recon in force. The Mark XXVII weighed 11,000 metric tons with a maximum normal speed of 110 km/h.

Mark XXVIII Bolo (Triumphant)

The Mark XXVIII entered service in 3186, and was designed as a “generalist” Bolo for the newly formed independent brigades. It was physically very similar to the Mark XXIV, although its improved psychotronics made it far more effective. The Mark XXVIII weighed 15,000 metric tons with a maximum speed of 90 km/h.

Mark XXIX Bolo (Victorious)

The Mark XXIX entered service in 3190 and was designed as the heavy Bolo of the independent brigades. It mounted two 110cm Hellbores, a heavy load of indirect fire weaponry, and integral logistics and maintenance functions that could be extended to support the rest of the brigade (a feature that became standard in all proceeding Bolos). The Mark XXIX weighed 24,000 metric tons and had a top speed of 75 km/h.

Mark XXX Bolo (Magnificent)

The Mark XXX was introduced in 3231 just before the "Last War" between the Humans and the Melconian began. The Mark XXX incorporated counter-gravity systems which allowed it greatly increased mobility and even allowed short flights at 500 km/h at the cost of rendering the battle screens, internal disrupter fields, and main armaments inoperable while doing so. The Mark XXX also included enhanced hyper-heuristic, double battle screens which provided greatly enhanced protection against kinetic energy attacks and was able to siphon most of the energy from energy based weapons off into the Bolo’s own batteries, and a newly improved cold fusion plant. The Mark XXX weighed 17,000 metric tons with a top speed of 115 km/h.

Mark XXXI Bolo

The Mark XXXI entered service in 3303. The Mark XXXI was an enhanced Mark XXX armed with a 200cm Hellbore (rated at 5 megatons/second), twelve 20cm Hellbores as infinite repeaters, and a host of smaller weapons for close in defense. The Mark XXXI had reduced indirect fire capabilities in favor of making it an assault vehicle, and in this regard it was given much heavier duralloy armor with an average thickness of 90cm, and a maximum thickness of 1.5m on the front glacis and turret faces. Secondary and tertiary weapons were mounted outside this primary hull to prevent damage to them disabling more important components. The Mark XXXI weighed 19,000 metric tons, but maintained the same speed as the Mark XXX.

Mark XXXII Bolo

The Mark XXXII was introduced in 3356 and is the last Bolo for which such an exact date is known. The Mark XXXII was in essence a Mark XXXI that was able to form a direct human-Bolo neural-psychotronic link. The Mark XXXII also had attachment points for a counter-grav sled to be attached, allowing it to assault drop from orbit without a lander. Offensively and defensively the Mark XXXII was almost identical to the Mark XXXI, with similar weight and speed.

Mark XXXIII Bolo

The year of introduction for the Mark XXXIII is unknown. The Mark XXXIII was much larger than any previous Mark of Bolo, weighing a massive 32,000 metric tons. It mounted three, independently turreted 200cm Hellbores with a secondary armament of sixteen 30cm Hellbore infinite repeaters and a massive indirect fire capability consisting of four 240cm howitzers, ten 40cm mortars, and a large VLS compartment. Because of its massive weight and armament, the Mark XXXIII was often referred to as a planetary siege unit. The total number of Mark XXXIIIs built is unknown, but doctrine called for them to be deployed in brigades of 24. The Mark XXXIII had a max speed similar to that of the Mark XXXII, but the Mark XXXIII also mounted an internal counter-grav system powerful enough to make orbital insertions.

Mark XXXIV Bolo

All though no exact date is known, the Mark XXXIV was introduced sometime between 3311 and 3408. The Mark XXXIV mounts two Hellbores, mortars, and two Hellrails. The Hailrail is a 60m long railgun with a yield of 90 megatons per bolt and were designed to provide orbital cover for Bolo brigades as they were able to engage ships before they entered orbit. Nothing is known about the weight of the Mark XXXIV, but it has a combat sprint speed of at least 200km/h.
