The M1128 Mobile Gun System is a modified Stryker, which in turn is a modified MOWAG Piranha. It utilizes a 105mm rifled cannon and is designed to provide direct fire-support to troops in low-level conflicts and light anti-armor support. It is also designed to be air-mobile, so it can be part of a rapid reaction force.
— Battlelog description
The M1128 is a Tank Destroyer featured in Battlefield 3: Armored Kill. It has the chassis and troop carrying capacity of an IFV with the same cannon capability as a MBT, yet moves and shifts after expelling rounds and generally lacks stability. Due to its lack of armor compared to other vehicles, it must rely on speed and maneuverability when facing other armor.
