MARINE CORPS BASE CAMP PENDLETON -- More than 25,000 reservists a year train at the Reserve Support Unit nestled in the heart of Camp Talega, the northern-most camp here.The RSU ensures more than 250 reserve units are taken care of when they come to Camp Pendleton to prepare for different contingencies.If Marines were ever to do something like Desert Storm again, the RSU would turn into the Mobilization Support Battalion, said Capt. Jason Wallace, logistics officer, RSU.?We can process 1,000 inactive ready reservists per week,? Wallace said.Processing includes the issuing of clothing and dog tags, checking medical and service record books ensuring there are no any pay or legal problems, and that the Marines are physically prepared, he said.After the reserve unit is processed, it is then redesignated the Mobilization Training Battalion, Wallace said.The MTB then goes through combat refresher training such as, rappelling, rifle range and ordnance.After training, the battalion becomes the Combat Replacement Command. If there were a contingency, the CRC would relieve a command in place in the area of operations, Wallace said.Other than providing training for contingencies, the RSU coordinates training on Camp Pendleton for various Marine reserve units during their two-week active duty for training cycle. The RSU also coordinates requests from other agencies like ROTC, police and fire departments, even other countries like the British Royal Marines.?The 25th Marine Regiment conducted an amphibious landing on Red Beach during the Amphibious Orientation Training 2000,? Wallace said. ?What we did for them was coordinate the logistics support, which was locking on training areas and air space and coordinating physical support, to include all contract services,? Wallace said.The RSU also provided transportation of 25th Marines gear and personnel, coordinated fuel, and post exercise support such as fiscal closeout, he said.If the reserve unit requires billeting, the RSU has 28-person Quonset huts which can accommodate 658 Marines. If the reservists want to train, they have to come through us,? said SSgt. Charles Evanson, supply chief, logistics chief, special services officer and much more.?We have as many billets as a battalion, but only 20 enlisted Marines and four officers, so many Marines carry more than one title,? Evanson said.Even short-handed, RSU gets the work done.?It is like feast or famine here.? Evanson said. ?We either have extreme amounts of work to be done or none at all. We have to react to what is going on around here.?The best part of this job is when units come back and say thanks. It doesn?t happen often, but it?s nice when it does,? he said.
