The GFF4 (Geschützte Führungs- und Funktionsfahrzeuge, Klasse 4: Protected Command and Functional Vehicles, Class 4), previously KMW Grizzly, is a medium weight MRAP armored personnel carrier, developed by Krauss-Maffei Wegmann (KMW), designed for operation with the German Army based on the 6x6 Trakker chassis from Iveco adapted to meet the needs of the German Army.

[1] It is being developed under the direction of the German Ministry of Defence Federal Office of Defense Technology and Procurement (Bundesamt für Wehrtechnik und Beschaffung).

Grizzly can carry 10 fully equipped troops, which exceeds by greater than 50% the 3 tons required by the German request for proposal (RFP).

The driver's station and crew compartment form an integral safety cell providing protection against improvised explosive devices (IEDs), projectiles, missiles and mines.

KMW is offering the vehicle in several configurations, and since the design is based on a modular concept, a smaller 4x4 or larger 8x8 variant, with corresponding payloads are possible.
