I believe the shield on the second halftrack is for the 37mm gun with twin 50cal MG's on either side. A rare vehicle...
The first one is a M16, the second one is a M16A1 converted off a M3. The shields, know as "Bat wings" were used quite a bit on M16s in the `50s starting in Korea.
Many, many changes.
You think, Joe? lol. I spent a lot of time at Riley from `93 to `04. I was down there about a year ago, it'd been a couple years since I'd been down there, and about the only thing that looked the same to me was Maits. They've built the hell out of the place. How about all the new barracks down by and on Funston. The Ogden gate is big time now. And the Mega motorpools up across from the old PX. It's like a whole new post.
No sign of the 2S1, M577 or ZSU-23-4 at MATES?
Since Joe found that AMX-30 on 18C, I think I'm gonna have to run down there this week and get shots of it. I'll check on the ZSU and 2S1. As far as M577s, there are dozens of them down there.
