The soviet troops look too 'bunched up' with large front profiles exposed. I like to see soldiers making maximum use of cover with just a gun barrel and a minimum amount of target presented.
The sniper would not be operating so close to the line troops.
The Soviet troops seem to 'shine' the clothing would be dull / dusty in that environment.
Interesting comment on the US troops, I did not realize field applied camouflage on a personal weapon was considered 'damage' by Uncle Sam.
If it prevented a few less bullets aimed at me the cost would seem insignificant, living to tell about it after the tour is priceless. Besides the Army's cost per weapon at their volume discount shaves a few Franklin's off each firearm.
