I like em both. But the early period could pull double duty for warm weather Korea War. I will have to check for the Army, but I know the ROK Marines used old USMC uniforms or at least of the same cut. Before switching over to the camo style after being in theater for a few years.
Don't know if they would pass for well kitted out ARVAN ether, that is before every one and his mother was running around with m16s that is.
So Yeah, I could see myself picking up the m1, m1 carbine, BAR, 30cal armed ROKS.
