Dana Guy, an operational adviser and primary subterranean operation and heavy breach trainer for the U.S. Army Asymmetric Warfare Group, coaches a soldier from Company B, 1st Battalion, 6th Infantry Regiment, 2nd Brigade Combat Team, 1st Armored Division of the Brigade Modernization Command in using a tactical torch system to cut through a simulated steel door during the AWG’s Subterranean Risk Reduction Exercise. During the exercise, the soldiers were taught various levels of breaching operations and provided hands on experience with using the tools on surface and within the subterranean environment. The AWG conducted the exercise in order to prepare the soldiers for their upcoming participation in a subterranean assessment at the Network Integration Evaluation 14.1 scheduled for November. AWG’s end state for conducting the Risk Reduction Exercise and its upcoming participation in NIE 14.1 is to develop technique solutions to capability gaps with respect to subterranean operations and to ultimately develop an Army Techniques Publication on subterranean warfare for the force.
