Based on a modified and refurbished M1 Abrams tank chassis, the GRIZZLY will employ armors and many components derived from various members of the Abrams family of tanks. The system employs a two man crew. Its mobility will be comparable to the Abrams Main Battle Tank and the Bradley Fighting Vehicle. The dominant maneuver force will support the GRIZZLY with ongoing direct and indirect fire and air support. The GRIZZLY will be deployed with selected engineer companies in mechanized battalions, armored cavalry regiments, and heavy brigades. GRIZZLY is employed as an integral part of the M1A2 SEP/M2A3 equipped digital maneuver battalion task force. GRIZZLY as part of the Breach Force and supported by friendly direct and indirect fires, will reduce threat obstacles and create a safe one way passage lane for an M1/M2 equipped force to follow. A GRIZZLY equipped task force can execute breaching operations with minimal preparation and with little or no loss of task force momentum or need for lane proofing.
GRIZZLY must provide an integrated, survivable breach system. GRIZZLY must provide breach lanes through simple and complex obstacles that allow the supported maneuver force to pass through and accomplish the force's mission. The required probabilities of two GRIZZLYs to successfully breach a lane is 0.95 (threshold) and 0.99 (objective), inclusive of blade and system losses due to mines, but exclusive of losses due to direct and indirect fires. GRIZZLY must breach lanes through simple and complex obstacles to allow the heavy maneuver force to conduct Decisive Operations. The probabilities of the GRIZZLY in providing breached lanes are a function of the GRIZZLY旧 breach capabilities and GRIZZLY survivability to direct and indirect fires, but also the success of the maneuver force at suppressing the enemy (threat) force, obscuring the breach site, and securing the breach site. Nearly all obstacles include mines, so survivability of the system and the blade to mines must be considered.
Doctrine calls for two lanes per task force with a recommended allocation of two assets to achieve one lane. The GRIZZLY equipped force must provide the task force a near certainty (a 99% probability) of achieving one lane and a high probability (approximately 90%) of achieving two lanes. Assuming that two GRIZZLYs are allocated to each of two lanes, the threshold value of 0.95 results in a 0.90 probability of successfully breaching both lanes and a 0.9975% probability of successfully breaching at least one of the lanes. GRIZZLY will provide a lane allowing 95% of the maneuver task force (threshold) and 99% of the task force (objective) to safely pass, excluding losses due to direct and indirect fires.
GRIZZLY will operate as part of a combined arms task force. The maneuver commander sets the conditions for breaching success through the execution of the Suppress, Obscure, and Secure fundamentals of breaching. Ideally, direct and observed indirect fires on the breach site are eliminated before the GRIZZLY is committed to execute the Reduce fundamental of breaching operations. Force on force combat simulation and threat assessments predict that the most likely direct fire threat faced by the GRIZZLY will come from dismounted teams providing fires on the obstacle and employing handheld anti-tank weapons (RPG type weapons). GRIZZLY is also exposed to indirect fires while conducting the breach. The specified conditions are representative of the type of fire mission expected against the GRIZZLY in the breach. These conditions equate to 60 rounds aimed/targeted at a box approximately 250 meters by 50 meters deep. These parameters will provide the inputs to existing models for development of the specific test parameters to measure compliance with this requirement. It is not intended that testing include the firing of 60 shells. GRIZZLY will provide resistance to perforation of the CCS against a 6-gun artillery battery, firing a variable time fuze, 10 round artillery salvo of 155 mm M107 high explosive with proximity fuze comparable to the M728 from 7,000 meters (threshold). The objective requirement is to provide resistance to top attack munitions.
