Found that out the hard way on like my second or third tutorial mission. One dropped down from the sky and immediately overwatched right next to my most experienced unit. Which was fine, just hunkered down til I could get backup over there
Nah, next turn thin man picked him off while being hunkered down AND behind half cover. GG. Totally my fault for letting him get shot up before that tho, I misread some positioning and thought he was behind cover. NOPE, half his HP gone
Thin Men use Light Plasma Rifles, which has a +10 Accuracy modifier. Don't expect them to lose much. ---
