Round Two of "Name that Vehicle!"

[sapper740]

Good evening Ladies and gentlemen! Welcome to round two of "Name that Vehicle!" For those of you who missed round one, here are the rules:
I'll post a pic of an obscure military vehicle. After each unsuccessful guess I'll post a clue. The grand prize of a six pack of "Lone Star" beer will be reduced by two beer for each subsequent clue I give.
The winner of the first round of "Name that Vehicle" was Alex Blair of Ottawa, Canada. Alex came closest with his guess of a Sisu xa200. The vehicle in the pic was actually a Sisu xa180, however the judges ruled Alex's guess was close enough. That plus the fact that three clues had already been given and it wasn't going to cost the sponsor a cent!
So! Everyone understand the rules? Good! Hands on your buzzer, it's time to play, "NAME THAT VEHICLE!"
