There is one in one of those snowy maps. It is on top of an unreachable height by the flag, standing right at the edge. Everytime I climb in through the front walls, I mistake it for a ranged bastard and practice extra caution for a brief period of time. Then I realize that it is a prop added by the troll map designer. Takes me a few seconds to shake the stupidity off of me and go on marching for the flag.
