A data network specialist from Headquarters Regiment, 1st Marine Logistics Group, communicates with an MV-22 Osprey pilot during an en-route care exercise aboard Camp Pendleton, Calif., Jan. 28, 2015. During the four-day exercise, corpsmen trained to prepare a Special-Purpose Marine Air-Ground Task Force group that is going to forward deploy later this year. The more than 40 corpsmen set up a shock trauma platoon facility, or mobile emergency room, to treat simulated casualties. The casualties were stabilized in the STP and then flown out via aircraft.
