For heroism in ground combat against a hostile force in the Republic of Vietnam on 8 October 1968. Specialist Four Lambert distinguished himself by while serving as a team leader with Company A, 3rd Battalion, 187th Infantry. Company A was moving by convoy from Fire Support Base Patton II to Cu Chi, Republic of Vietnam, when one of the vehicles received direct hits by rocket propelled grenades. Shortly after the initial attack, the enemy opened up with small arms and a fifty caliber machine gun. While the company waited for the evacuation helicopters to arrive after the attack, the disabled truck, which was loaded with explosives, began to burn. When it became apparent that throwing water on the blaze was futile, Specialist Lambert, disregarding his own safety, jumped aboard the burning truck and extinguished the blaze. Specialist Lambert’s action exposed him to injury or death from the burning explosives and any remaining enemy troops in the area. Through his courage and outstanding leadership, he contributed immeasurably to the success of the mission. Specialist Four Lambert’s personal bravery and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit. And the United States Army.
