The Grizzly [initially designated the Breacher] is an armored vehicle designed to breach complex obstacles including mines, berms, wire, rubble, and tank-ditches. The GRIZZLY will breach obstacles with minimal preparation creating safe lanes for other vehicles in the dominant maneuver force with little or no loss in momentum. The GRIZZLY's obstacle clearing features include a full-width mine-clearing blade and a powered, extensible excavating arm. GRIZZLY is a Military Load Class 70 complex obstacle breaching vehicle which will integrate advanced countermine and counter-obstacle capabilities into a single survivable system. GRIZZLY will incorporate a full width Mine Clearing Blade (MCB), Power Driven Arm (PDA) for obstacle reduction and digging and a commander's control station (CCS) (crew compartment). It will have a remote fired 50-caliber machine gun and grenade launched screening smoke for self-defense. GRIZZLY will breach an 600 meter complex obstacle in 21 minutes and breach an antitank ditch in 5 minutes. GRIZZLY will be capable of breaching other types of natural and man made, simple and complex obstacles, creating a lane for vehicles to follow. It will integrate the technologies incorporated in the M1 & M2A3 chassis with the GRIZZLY mission modules. GRIZZLY is designed to provide the Digital Division with mobility support (i.e. counter-obstacle breaching) for Decisive Operations.
