English: The tartan officially named "Red MacDuff (Government No. 16)" by the UK Ministry of Defense, and used in some regimental attire (including cap cockade and bandsmen uniforms) of the 154 (Scottish) Regiment RLC [1] (though it is no longer "funded" as part of the MoD uniform specs [2]). The 154th began as a Lowland regiment, and after amalgamation became a pan-Scottish one. This regimental tartan is closely based on the most conventionalised of the MacDuff tartans (the main Wilsons of Bannockburn sett), but has a proportionally smaller green area.

The overall pattern is basically the same as that of royal Stewart, but without the latter's yellow and white over-checks. It is possible that a version of what is now MacDuff was ancestral to the Stewart sett (though the earliest directly attested recording of a MacDuff variant was c. 1815-1820 in the Highland Society of London records, while the Stewart variant known as Prince Charles Edwart Stuart has been identified in surviving cloth samples from the mid-18th century, and is one of the oldest setts in continuous production [3]. The MacDuffs have been familialy connected to the Stewarts of Albany since the late 14th century.

This image is not exactly full-sett, and cannot tile horizontally and vertically; this centred and zoomed-out version was created for tabular comparison to other regimental tartans. Scottish Register of Tartans does not have this sett, and it is not available from the MoD, either, and is probably only on file with the regiment somewhere and with whatever weaver they are using. This image and the thread count for it are approximations based on careful examination of regiment members in uniform (e.g. [4]).

This is a usual, mirroring tartan. Thread count (in "/" notation): /R72 BB18 K24 G28 R20 K6 R20/ (or in boldfacing notation: R72 BB18 K24 G28 R20 K6 R20), where BB = Balmoral blue, though for this image I edited the colour to be somewhat between Textile32's Balmoral blue and ancient blue, to match the regimental photos as closely as possible. It definitely uses a lighter blue than the typical dark "tartan" blue (as usually do all the other MacDuff tartans aside from the Vestiarium Scoticum version which has the darker "standard" blue).
