Skorpion, you can litteraly see only the forward 6", the end of the gun barrel, and the barrel of a .50. You can't see the gun shield, you can't see the front. It could easily be the M10 (but I don't think so, given its similarity to the M4).
And IDK about the perk price. A single pass from a 109K and this thing should be turreted, engine killed, and possibly flat out dead.
