Crosshairs

Meticulous, cautious, some would say overcautious—won't take a shot unless he's sure he can't miss... won't waste ammo. Pinpointer, his dual rocket-propelled grenade launcher, can lock on target in less than .0003 seconds, but usually trusts Crosshairs to decide when to shoot. In vehicle mode, maximum speed: 160 mph, range: 750 miles; built for traversing rough terrain.
