The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pride in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star (Posthumously) to Sergeant Robert Irwin Meeker (ASN: US-52756568), United States Army, for gallantry in actions while engaged in military operations involving conflict with an armed hostile force on 18 February 1969 while serving with Troop L, 3d Squadron, 11th Armored Cavalry Regiment, in the Republic of Vietnam. On this date Sergeant Meeker was serving as section leader of a scout element which was conducting a routine reconnaissance mission. Suddenly the armored column was raked by automatic weapons and antitank grenade fire. In the initial burst of fire, Sergeant Meeker’s vehicle sustained a direct hit from a rocket propelled grenade round knocking him from the vehicle and severely wounding him. Although wounded and dazed, he remounted his vehicle and began directing accurate and deadly machine gun fire upon the hostile elements. While engaging the enemy forces from his vehicle he was again hit by enemy small arms fire. Nevertheless, he continued to man his position. Suddenly his vehicle received another direct hit from an enemy rocket propelled grenade round, wounding his entire crew and causing the vehicle to erupt into flames. Yet, he continued to shower the enemy positions with machine gun fire, pining the hostile elements down long enough to allow the evacuation of his wounded comrades. For a third time his vehicle was hit by a rocket propelled grenade round, again knocking him to the ground. In spite of his severe wounds, he refused medical attention until his wounded comrades had been attended to. Sergeant Meeker’s unparalleled courage, dedication to duty and concern for the lives of his comrades were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
