U.S. Navy Petty Officer 1st Class Gregory Juday, Expeditionary Combat Camera Training Department trainer, uses the instructor console to rotate the Humvee Egress Assistance Trainer, or HEAT, at Fort Eustis, Va., Feb. 27, 2013. The trainer allows units to rehearse under controlled conditions and physically execute necessary steps required to survive a vehicle rollover, allowing occupants to gain experience in how to orient themselves, collect any injured individuals and successfully exit the overturned vehicle.
