Staff Sergeant Lambers' official Medal of Honor citation reads: "For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty.

The unit had established a night defensive position astride a suspected enemy infiltration route, when it was attacked by an estimated Viet Cong battalion.

Lambers assisted in the repair of the weapon and directed canister fire at point-blank range against the attacking enemy who had breached the defensive wire of the position.

He displayed great skill and valor throughout the 5-hour battle by personally directing artillery and helicopter fire, placing them at times within 5 meters of the defensive position.

He repeatedly exposed himself to hostile fire at great risk to his own life in order to redistribute ammunition and to care for seriously wounded comrades and to move them to sheltered positions.
