A rapidly reconfigurable, sustainable replacement

The Gauntlet is built as a rapidly reconfigurable and sustainable replacement solution for unsafe metal shipping containers — a common but hazardous stand-in for CQB training props. In its place, the Gauntlet gives units a ballistic-rated, modular structure built specifically for live-fire training.
