KAHUKU, Hawaii -- KAHUKU, Hawaii - Marines with Maintenance Co., Combat Service Support Group 3, MCB Hawaii, Kaneohe Bay, took part in five days of training here from Nov. 17 - 21. They defended themselves in high-stressed, combat situations and still completed the mission at hand. The Group Marines responded to situations that required quick decisions while defending their perimeter. Topics covered included training with vehicle checkpoint procedures, security and defending perimeters for combat service support areas (CSSA), and security patrols and maintenance contact team convoy operations.The first three days of training consisted of classes and practical application. Day one involved land navigation, day two was mainly patrolling, and day three mostly convoy operations and night driving. Days four and five challenged the Marines' skills with 48 hours of tactical operations. The Group had to pull together everything it had learned. The two-day test of training proved CSSG-3 Marines are prepared for whatever circumstances that could potentially arise.During the night convoy, Group Marines experienced everything from ambushes and sniper fire, to roadblocks and heavy machinegun fire."The Marines responded well to the attacks," said Maj. Patrick Wall, commanding officer of Maintenance Co. "They performed really well at stopping and returning fire. Keeping communications up was the only thing they started out shaky at."During training, the Group's staff noncommissioned officers played the part of the enemy; therefore, if a Marine wasn't wearing a flak jacket and a Kevlar, he was dangerous. Wall took part as an enemy; when he attempted to come into the CSSA, he was stopped immediately."I was very impressed with how they took me in," said Wall. "They used their heads and went through the procedures well."The Marines handled their hostage with force, but also with respect."All they have to do is apply what they've learned in real combat situations," said Gunnery Sgt. Micheal Golden, the company gunnery sergeant. "They got the job done, and still treated the hostage with dignity."The five days of training promoted small-unit leadership and allowed the Marines to teach and apply the lessons they had learned."All the Marines did what they had to do and learned the appropriate techniques to be successful out here in the field," said Golden. "The Marines really love getting out there, since we don't get a chance to get into the field as much as we would like to. But, you never can get in the field enough."The most difficult part of the training, said CSSG-3 Marines, was the fact that they only had five days to cover all topics. Yet, certain subjects are difficult to grasp completely, and especially in such a limited amount of time."We obviously hope to always come out more; the Marines learn a lot from training, and they enjoy it too," said Golden.The Marines also have future training schedules set up to further prepare them for combat situations. Until the next time, they will apply the training they received in the Kahukus Training Areas, and will add onto it as time goes by.
