Jets & Planes but no UAV's here.

I tend to ignore reserve units and legacy units ... also FOC, and look at probable deployments.

Example: At the start of the first Gulf War the USMC had a handful of M1's but acquired enough (regular and HA) that 50% of their fielded tank force (all of 2 battalions) was M1s. So I consider both the M60 ans M1 to be equally available from 1991 thru 1994.

In 1975-6 I was with an active duty unit that still used M14s as their primary (and only) rifle, yet the OOB doesn't show the M14 as being available as an option at that time.

So yes, there are "inaccuracies", but what's "probable" is what the OOB represents not what's "possible" (generally).
