A crew member with the 1st Battalion, 64th Armor Regiment, 1st Armored Brigade Combat Team, 3rd Infantry Division, performs maintenance on the main gun tube of an M1A2SEP Abrams Tank during Company Delta “Death Knights’,” Gunnery Table VI, held here at the Digital Multi-Purpose Range Complex, Feb. 7. The Company Delta ‘Death Knights,’ have been running 1st ABCT crews through GT II-VI crew-level qualification during the first two weeks of February. This gunnery has presented some unique challenges, as the Death Knight team has successfully validated 35 crews in the time usually allotted for validating a normal company size element of 10-15 crews.
