Not an actioned packed moment but a visual ""what the fuck" moment
OP Pine Plains in Fort Drum NY, we had just been dropped off by our lift at the secondary MOUT site, Mission was search and recover of a downed pilot. As we're walking up the hill we see the smoke from the downed helo and it's deadly silent. As we pop the crest there is a real live crashed AH1 Cobra gunship with smoke just pouring out of it, all effects mind you, but just the feeling of walking next to the crashed helo with smoke all over it being quite was a jaw dropping moment. Especially seeing the we got this Frago at dawn which just added to the visual effect. Very high up on the MilSim scale!
