The cameraman filming action of the battle
The sitting firing pose with sniperscope rifle. Notice the the feather in his helmet. I don’t think snipers would place a feather on their helmet today. 
Soldier with a shell. I really like detail Miklan puts on his figures. The figures are now available on Ebay for $54.90 plus postage.
Not doubt these figures are statues in plastic small toy soldier scale they go above beyond any toy soldier category ,too perfect to be true .not wonder the price.

I wonder if the sniper is supposed to be Carlos Hathcock? They called him White Feather, I believe.
indeed….
