3. Use the extracts from AR 75-1 and TM 43-0001-28 contained in the Appendix to fill out the blank DA
Form 4379-R on page 2-14. Use the following data on a hypothetical ammunition malfunction:
You are the ammunition officer/operations officer at ASP-1, operated by the 41st Ordnance Company (DS) at
Fort Comanche, Arizona 29917 (DOD activity address code [DODAAC] WG75AA). The unit that experienced
the ammunition malfunction is the 1st Platoon, Company A, 2d Tank Battalion, 5th Armored Division (DODAAC
WG73AA). The platoon leader is 1LT Rommel H. Klank.
The ammunition malfunction is a premature detonation in the bore of a tank. The malfunction occurred at 1430
on 12 August 1991, at Range 9, training area Bravo, during a tactical combat fire exercise for Operation Desert
Push. The gunner and the loader were killed, and the commander and the driver were badly burned.
The malfunctioning round was a 105mm high-explosive anti-tank-tracer (HEAT-T), C508. The tank had already
fired five rounds of APFSDS-T, C521, with no problem. The rounds were drawn this morning at about 0625,
transported to the staging area, unpacked, and placed in the tank ready racks at 0830. Each round was visually
inspected. No deficiencies were noted. The tanks were loaded on transporters at about 1100, and were
transported to the exercise rally points. They were unloaded by 1300 hours. The exercise began at 1345, with
temperatures over 100 F.
The weapon involved was an M60A1 tank with a 105mm cannon. The tank's serial number is 2261785. The
cannon's serial number is 161371. It was manufactured by Browning Engineering Corporation after August 1967.
The gun tube blew out about 2 feet behind the muzzle brake, the breech block blew out, and the interior of the
tank was extensively damaged by heat generated by the propellant. The other ammunition on board did not
detonate, but several rounds were extensively damaged before the fire could be brought under control.
