Rangers fought from the Demilitarized Zone near the North Vietnam border to the Mekong Delta. These missions provided valued intelligence and conducted a host of special operations against North Vietnamese Army and Viet Cong forces.

While conducting a long reconnaissance patrol, on 22 February 1969, in the Tinh
Phuoc Thanh province, Law's patrol met the enemy. Under intense attack, Law tried to outflank the enemy and provide suppressing fire against the attackers. Despite running low on ammunition and inspired by Law's attempted to fight, other members of the patrol counterattacked the heavily armed enemy. Law and the other Rangers face stiff opposition and came under small arms and grenade assaults. A grenade landed near Law's patrol. Without regard to his own safety, he threw himself onto the grenade to save five other Rangers' lives. For his extraordinary courage and selfless service, Robert D. Law received the Congressional Medal of Honor, posthumously.
