I found these pictures at the same sale where I found the photo in my previous post. They are of a military base in Korea in the early 1950's.
Googling Korean War insignias, I was able to determine the insignia on the helipcopter designated them as the 25th Infantry division out of Hawaii, also known as Tropic Lightning (how cool is that for a nickname).
Holding an M1 Carbine rifle.
The same helicopter from earlier. I think this is a Bell 47. I guess the skid could be swapped out with landing wheels?
I believe these are possibly South Korean soldiers.
This looks like a kid
Love the pompadour.
