The M2290 FAV (Force Application Vehicle) is as essential to the IIU as guns and helmets.
About this creation
The M2290 FAV is outwardly similar to the M2289, except it mounts a 14.5mm machine gun capable of firing 450 rounds per minute and shredding any known infantry or vehicle. It can be flipped by a well-placed grenade due to its light weight. Its massive disc brakes allow a near-instantaneous stop, lest the driver be ejected. The armor of the M2290 is toough, but it can still be punctured and melted by plasma weaponry.
The extra two wheels, extended troop bed, and M4 machine gun can be seen here.
