Ahh they must have been some what embarrassed to do that. They can easily get the grenade launcher back when the story goes away.
Although I don’t see why they think they need a vehicle that is made for a combat zone like Irag that can absorb RPG and AK-47 rounds.... What could they possibly need it for?
