MIL-A-12560 MIL-A-12560 has been replaced by seven versions since the release of MIL-A-12560 by the US Army Ordnance Division and the US Army’s Center for Materials Mechanics. In particular, in recent years, each version The applicable period is gradually shortened, and the frequency of updates is faster and faster. For example, MIL-A-12560F (MR), released June 13, 1983, has been replaced by a new version G on August 15, 1919, for a period of only one year and two months; released only six months apart The revised single I, the G version was modified and added.
