Didn't even notice but when I looked again at the subdued flag patch I noticed he's got a mini eotech on the front rail of that gun. My platoon sergeant would have lost his mind.

Mind explaining the "eotech"/platoon sargeant being upset, for us civilians? ;)

Eotechs are, generally, optics designed for close quarters combat (though there are limited instances where it would be appropriate on a gun like that...maybe on a long gun from an unstable platform like a helicopter and you have a big target). Think inside of a building where you're shooting around corners or short hallways and you need both eyes open for depth perception. I was a platoon leader (lieutenant) and the platoon sergeant is the senior enlisted man in the platoon who is the most experienced with the technical side of combat. My platoon sergeant hated when people just tried to "look cool" with the things they put on their kit or gun that made no practical sense.
