9. 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. 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 (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 cannon. 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 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 Brown Engineering
Corporation after August 1967. The gun tube blew out about two 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 was brought under control.
All firing has been terminated. The battalion commander and the DAO have been notified. The
damaged tank remains in place under security.
