CPT Anderson's detachment was patrolling the Afghanistan-Pakistan border when they heard rocket propelled grenade (RPG) and automatic small arms fire in the vicinity of an Afghani border checkpoint three kilometers away. Realizing that the checkpoint was under attack by Anti Coalition Militia Forces (ACM), CPT Anderson ordered the detachment to move forward to the sound of the guns to aid the besieged Afghan position. As the detachment neared the checkpoint, CPT Anderson's vehicle came under heavy automatic and small arms fire from the ACM forces. CPT Anderson immediately stepped out of his ground mobility vehicle (GMV) and began engaging the enemy position with his M-240B machinegun. Standing by the GMV, exposed to enemy fire he killed one enemy soldier eliminating the obstacle while the other GMV bounded behind him. He then requested Close Air Support (CAS) and calmly sent a detailed status report over the radio. Pressing the fight, CPT Anderson ordered the detachment to move forward to close with and engage the enemy. When his vehicle became stuck while traversing a dry riverbed, he dismounted and went forward with another team member to an exposed hill in order to provide covering fire while his crew worked to free the GMV. While on the hill, CPT Anderson engaged two more enemy positions, killing one enemy soldier and causing three others to flee. As he was focusing the detachment's fires onto enemy positions with tracer rounds from his M-4 carbine, he was directly exposed to enemy fire and struck in the right leg by debris caused by enemy rounds impacting around his feet. During that time, a RPG exploded directly behind his position. Unwavering, CPT Anderson stayed forward, occupied the hill and prevented the enemy from maneuvering on his detachment. Once the vehicle was free, CPT Anderson kept the detachment bounding forward until he had the enemy trapped between his forces and the mountains. Unable to move any further forward due to impassable terrain, he positioned both GMV s in attack by fire positions. CPT Anderson then dismounted alone and moved 25 meters forward between the two GMV s to designate targets for his team with tracer rounds and ground commander laser pointer (GCP-11). While personally engaging another enemy position, a second RPG exploded 150 meters to his right as the enemy increased their fire in order to mask an attempt at retreat towards the Pakistan Border. The enemies' withdrawal was blocked by the detachment's location and the fire directed by CPT Anderson. CPT Anderson calmly remained in the exposed forward position engaging the enemy and focusing fires until two AH-64 Apache Attack helicopters came on station. CPT Anderson guided the two AH-64 Apache Attack helicopters in on the enemy positions with the GCP-11, enabling them to engage and kill 1 7 more ACM soldiers. Due to the direct actions of CPT Anderson, the detachment was able to close with and destroy a numerically superior enemy force during close and continuous fighting that saved the border checkpoint from certain annihilation. CPT Anderson acquitted himself valiantly in one of the largest combat engagements of Operation ENDURING FREEDOM. The leadership, courage, warrior spirit and dedication to duty displayed by CPT Anderson reflect great credit upon himself, the Combined Joint Special Operations Task Force-Afghanistan, and the United States Army.
