Greetings, I'm a film student, and for my next project there is a quick scene in the mountains of Afghanistan in 2010 involving a solitary United States army troop standing watch on a cliff on a cold, lonely night. Sorry if this is a newbie question, but I know very little about the military...what would such a soldier be wearing? He'll probably only be visible from the waist up. I have no sewing ability, but I do have friends who can sew. Would it be cheaper to get the outfit made, or to buy it at a surplus store? What all would I need? Thanks!
