A United States Army officer shares a modified combat rig that could offer service members a more optimized alternative to the traditional TAPS, or tactical assault panel system. In November, we spoke with 1st Lt. Zachary Calderone of the 25th Infantry Division during the Army's Joint Pacific Multinational Readiness Center, or JPMRC, training exercise in Hawaii. JPMRC is a large-scale 10-day training exercise where the US Army, along with international partners, utilizes realistic combat scenarios that prepare soldiers for battle with peer adversaries like China.
