181013-N-GQ656-903 FORT MCCOY, Wis. (Oct. 13, 2018) Master-at-Arms 2nd Class Casey Clark of Navy Operational Support Center (NOSC) Madison operates the HMMWV Egress Assistance Trainer (HEAT) at U.S. Army Garrison Fort McCoy, allowing Sailors to experience a simulated vehicle rollover during Mobilization Exercise (MOBEX) 2018. Clark received his HEAT Instructor certification earlier in the day. NOSC Madison holds MOBEX each year to provide Sailors a change-of-pace from a regular drill weekend and help ensure each one is familiar with the weapons and equipment required for them to mobilize downrange.
