American units with the highest percentage of casualties per conflict
During warfare, some units take more casualties than other units. Sometimes, the casualty rate is disproportionately high. This article displays the highest percentage of casualties among American units, including those wiped out as an effective force.
The term casualty in warfare can often be confusing. It often refers not to those that are killed on the battlefield but to those who can no longer fight. That can include disabled by injuries, disabled by psychological trauma, captured, deserted, or missing. A casualty is just a soldier who is no longer available for the immediate battle or campaign, the major consideration in combat. The number of casualties is simply the number of members of a unit who are not available for duty. For example, during the Seven Days Battles in the American Civil War (June 25 to July 1, 1862) there were 5,228 killed, 23,824 wounded and 7,007 missing or taken prisoner for a total of 36,059 casualties.[1][note 1] The word casualty has been used in a military context since at least 1513.[2]

[edit]Notes
[edit]- ^ Union and Confederate numbers added together
- ^ The 215 casualty figure is disputed. Morning muster on July 2 for the eight companies (A,B,D,E,G,H,I & K) involved in the suicidal attack was 262, and evening muster on the same day was 47. To arrive at the casualty figure of 215, the Regimental Historian (Lt. Wm. Lochren) subtracted the muster figures (262-47=215)(82.1%) and asserted that "[every one of the] 215 [missing men] lay upon the field."[5] Conducting an enumeration by individual names in 1982, Robert W. Meinhard of Winona State University accounted for only 179 (68.3%) casualties for the single day of July 2, 1863.[6][7] Presumably, Meinhard's and Lochren's conclusions are each based upon the same handwritten records from the regiment; accounting for the disputed 36 (=215-179) soldiers is the prerogative of the reader.[8]
- ^ 1915 to 1917 infantry regiments grew from 959 to 3,720 men and 112 officers [24]
- ^ 1st Marine Division was the unit with most casualties suffered during the Korean War with 29,868; including 4,004 KIA and 25,864 wounded. Regarding killed in action the 2nd Infantry Division was the unit with the highest ratio with 7,094 KIA and 16,575 wounded.
- ^ 1st Cavalry Division was the unit with most casualties suffered during the Vietnam War with 32,036; including 5,444 KIA and 26,592 wounded. Regarding killed in action the 1st Marine Division was the unit with the highest ratio with 7,012 KIA.
- ^ 1/9 Cavalry Major Donald Radcliff, the 1st Cavalry's first combat death, who was killed on 18 August 1965 while supporting U.S. Marines in his helicopter gunship during Operation Starlite.[30]
- ^ The 14th Quartermaster Detachment suffered the greatest number of casualties of any allied unit during Operation Desert Storm when an Iraqi Al Hussein Scud missile destroyed the installations the unit was located, after the failure in a Patriot air defense system that did not tracked the Iraqi missile location.
