POHAKULOA TRAINING AREA, ISLAND OF HAWAII, Hawaii -- The training experiences for Combat Service Support Group 3 that are taking place here on the Big Island of Hawaii, Feb. 4, just wouldn't be complete without plenty of attacks from opposing forces, or aggressors.Fifteen Marines clothed in desert camouflage gear, and acting as a guerrilla force, are determined to probe the lines and hit the Group area in hopes of preventing its Marines from completing their mission: supporting infantry battalions in a time of war. The aggressors would soon move towards the camp, look for weaknesses and infiltrate through, to take what they could to disrupt CSSG-3's mission.First Lt. Juan L. Reyna, supply officer for Supply Company, CSSG-3, and Sgt. Theodore F. Schmit, the platoon sergeant for the opposing forces, led the group of attackers."Our main mission throughout the duration of this training is to give the [CSSG-3] Marines a scenario that forces them to deal with terrorist combatants and put them in a situation that forces them to think fast, and act fast," said Schmit.The overall goal was also to teach them better offensive tactics, mainly patrolling tactics, since going on patrols and practicing signals prepares them for future missions, Schmit further explained.Although CSSG-3 Marines and Sailors aren't used to the elevation and extreme weather changes throughout the day at PTA, they are staying extremely motivated through it all, said Reyna."They are really getting into that tactical mindset that they need, and they are really eager to learn," he added. "There are no complaints from these Marines."Supply Co. Marines patrolled the area Feb. 4 and encountered attacking forces. Staff Sgt. Edward S. Garcia, training staff noncommissioned officer in charge, CSSG-3, took Marines out on patrol to give them a taste of what it would really be like in combat, as opposed to just learning about field patrols in a classroom setting. The Supply Marines learned basic tactics, combat formations, offensive and defensive positions, immediate action drills and ambushes while outside of the camp a couple days."It's really rare that these Marines get a chance to get out and do this," said Garcia. "I take everyone I can to do this because it's such good training."Combat Service Support Group 3 Marines and the aggressors met, fought and then discussed both their strengths and weaknesses when all was done. They shared what improvement was needed to correct mistakes, but overall, all agreed both sides performed very well.The scenarios were the first of many that would occur at PTA. The Marines say they are aware of what is to come, and they will remain cautious and ready for any and all scenarios that may come.
