I know the cav units had shields for the M-2 and M-60 on their M-113s in Vietnam. It was long ago, so my memory may be off. I think they were made in-country.
I like to have killed myself hitting my head on the ceiling in one of those things standing up too quick,I do
think I remember some with the 60s with shields.And some on
the 2 1/2 ton gunships escorting convoys,in-country mfg,bet
your right
were you surprised to find out those APCs were made
of aluminum,I know I was.Unpleasntly surprised
Indeed. The first ones were made locally, later ones built back in the states and Korea once their usefulness was proven.
At first, the tracks belonging to the cavs that had the gun shields and other useful additions were known as A-Cav tracks to differentiate them from our *slick* Infantry and Combat Engineer haulers. Later the gun shields started turning up on all sorts of things, including convoy trucks and MP vehicles.
Official version of what an M113 was supposed to look like:
ACAV M113 with gun shields and extra M60 MGs fitted in back, 1966
Instant gun truck!
