The Distinguished Service Cross is presented to Fred Ogas, Jr., Sergeant, U.S. Army, for extraordinary heroism in action in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Troop C, 3d Squadron, 4th Cavalry, 25th Infantry Division. Sergeant Ogas distinguished himself by exceptional valorous actions on 19 June 1969 during a reconnaissance- in-force mission. When a large well-entrenched enemy force opened fire on his troop, the commander and several other officers were killed or wounded as antitank rockets struck their tracked vehicle. Sergeant Ogas was thrown from his vehicle and wounded. Despite his wounds, he immediately moved to the aid of his injured comrades. As he was evacuating two officers, deadly fire erupted from an enemy bunker nearby. Sergeant Ogas single-handedly stormed the hostile fortification and killed the enemy soldiers with rifle and hand grenade fire. Returning to the wounded officers, he succeeded in evacuating them out of range of direct fire. Realizing that the troop was without command, Sergeant Ogas quickly assumed control of the unit and reorganized the now-scattered men. Establishing communication with the squadron commander who was aloft in the command and control helicopter, Sergeant Ogas assembled the casualties and guided medical evacuation helicopters into the contact area. After moving his men to a selected night position, he accomplished contact with and successfully directed another troop to his location. He retained control of the unit until an officer could be inserted into the area. Sergeant Ogas' extraordinary heroism 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.

The Distinguished Service Cross is presented to Vincent H. Okamoto, Second Lieutenant (Infantry), U.S. Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company B, 2d Battalion, 27th Infantry, 25th Infantry Division. Second Lieutenant Okamoto distinguished himself by exceptionally valorous actions on 24 August 1968 while serving as a platoon leader with an infantry unit near Dau Tieng. A ground attack was launched against his battalion's night location by three reinforced North Vietnamese and Viet Cong companies. The initial assault destroyed a strategic section of the perimeter. Under heavy automatic weapons, small arms and rocket-propelled grenade fire, Lieutenant Okamoto moved with five of his men to restore this vital position. Realizing the need for supporting fire, he ran to a partially destroyed armored personnel carrier and manned its machine gun. After the weapon malfunctioned, he dashed through the fusillade of enemy fire to a second and then a third carrier to place suppressing fire on the aggressors. Spying a group of enemy soldiers maneuvering toward the unit's lines, Lieutenant Okamoto crawled under cover of small arms and automatic weapons fire to less than ten meters from the communists and destroyed them with fragmentation grenades. He was injured by a hostile concussion grenade, which exploded close to his position, but refusing aid he kept fighting until the North Vietnamese/Viet Cong force was defeated. Second Lieutenant Okamoto's extraordinary heroism 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.

He and a squad leader fought their way to within a short distance of the nearest bunker. Lieutenant O'Kusky then crawled into the open and threw a hand grenade into the fortification, silencing its occupants. While advancing alone towards the next hostile position he was wounded in the thigh by enemy fire. Ignoring the pain of his injury and the communists' fusillade, he continued to close on the emplacement and threw a grenade which partially destroyed it. As Lieutenant O'Kusky released the grenade, he was fatally wounded by a burst of automatic weapon fire from a third North Vietnamese fortification.

Oliver, J. L.

The Distinguished Service Cross is presented to J. L. Oliver, Staff Sergeant, U.S. Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company C, 1st Battalion, 8th Infantry, 4th Infantry Division. Staff Sergeant Oliver distinguished himself by exceptionally valorous actions on 6 May 1967 while serving as squad leader during a search and destroy mission near the Cambodian border. As the friendly units moved through dense undergrowth, Sergeant Oliver detected movement to his right front. Without hesitation, he ordered his machine gun and grenade launching crews into action. While a platoon provided a base of fire, Sergeant Oliver led his squad toward the Viet Cong emplacements. He spotted several bunkers and cautioned his men to take cover. While they engaged the insurgents with rifle and machine gun fire, he bolted towards the first fortification, threw a grenade inside, and killed all of its occupants. Again exposing himself to the hostile barrage, Sergeant Oliver ran to the next Viet Cong bunker and was successful in blowing it up. He then fired on the remaining insurgents with extreme effectiveness. His aggressive moves throughout the engagement seemed instinctive and without regard for his own safety, and his destruction of the Viet Cong fighting strength saved his unit from summering many casualties. He was credited with seven insurgents killed in action and many wounded. Staff Sergeant Oliver's extraordinary heroism 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.

The Distinguished Service Cross is presented to Daniel L. O'Neill, First Lieutenant (Infantry), U.S. Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company C, 1st Battalion, 501st Infantry, 101st Airborne Division (Airmobile). First Lieutenant O'Neill distinguished himself by exceptionally valorous actions on 21 May 1969 while serving as platoon leader on a search and destroy mission. His unit was ordered to attack a heavily-fortified hilltop position near the city of Tam Ky. A large open rice paddy lay between his position and the objective. Immediately upon initiating the attack, his platoon was subjected to heavy enemy automatic weapons and rocket-propelled grenade fire. Employing fire and maneuver, he began to move his platoon forward. Realizing that his men were reluctant to move because of the heavy volume of enemy fire, Lieutenant O'Neill began to move up and down the line shouting encouragement. He then took the lead and led his platoon across the rice paddy to the base of the enemy positions. Employing hand grenades and close fighting, his platoon broke through the initial enemy bunkers and continued to ascend the hill. He then realized that his platoon was receiving fire from its flanks and rear as well as from the enemy positions to the front. Temporarily halting his platoon, he directed the destruction of the enemy positions to his flanks and rear with light antitank weapons and hand grenades. He then renewed the assault, called for and redistributed ammunition, and led the final assault to the top of the hill, eliminating the final pockets of enemy resistance. Ordered to withdraw from the hill to reinforce another platoon, he effectively led his men against the insurgents and rescued the besieged elements. Lieutenant O'Neill's extraordinary heroism 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.

Specialist Four Oquendo distinguished himself by exceptionally valorous actions on 6 May 1969 while serving as a machine gunner at a fire support base in Tay Ninh Province. In the early morning hours, the base began to receive heavy rocket and mortar fire followed by a ground assault. When a North Vietnamese regiment armed with machine guns and satchel charges rushed the perimeter, Specialist Oquendo detonated claymore mines and placed rifle fire into their advancing ranks. As the enemy attempted to blast openings in the wire barrier, he valiantly attempted to abort their efforts. Soon, however, the enemy forces penetrated the berm in several spots and began throwing grenades and small arms fire at Specialist Oquendo's position. He and several others in his bunker were wounded, but he refused to be evacuated. When he depleted his ammunition, he grabbed one of his wounded comrade's weapons and continued firing. In a determined bid to capture his bunker, the communists stormed his position. During the hand to hand struggle, he was mortally wounded while defending his area. Specialist Oquendo's extraordinary heroism and devotion to duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.

As he was administering aid, an enemy grenade landed eight feet away. Specialist O'Quinn used his body to shield the man, and was hit in the leg by shrapnel. Disregarding his painful injury, he continued to treat his comrade and then maneuvered about the battlefield to care for the other wounded. After the fighting subsided, he refused evacuation until the other casualties had been cared for and extracted. Specialist Four O'Quinn's extraordinary heroism 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.

First Lieutenant O'Reilly distinguished himself by exceptionally valorous actions from 1 to 3 June 1968 as commander of an infantry company during a reconnaissance-in-force operation near the Cambodian border. A sister company was pinned down by an estimated battalion of Viet Cong firing small arms, machine guns, rockets and mortars from a well fortified bunker complex. Lieutenant O'Reilly attempted to lead his force to the beleaguered unit, but was stopped by the enemy's barrage. Disregarding his safety, he crawled twenty-five meters toward the nearest bunker and hurled grenades into it which killed its two occupants and silenced its deadly stream of automatic weapons fire. He then sprang to his feet and rallied his men for an assault on the remaining fortifications. In fierce close combat the Viet Cong abandoned their emplacements and broke contact. During the next two days the search for the elusive foe continued, and on 3 June contact was made again. As his unit came under intense automatic weapons fire, Lieutenant O'Reilly quickly moved his troops on line and assaulted the hostile positions. While deploying his men so they could effectively engage the Viet Cong bunkers with comparative safety, he was killed by a burst of enemy automatic weapons fire. First Lieutenant O'Reilly's extraordinary heroism and devotion to duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.

Orsini, Captain (Infantry), U.S. Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company D, 1st Battalion, 12th Cavalry, 1st Cavalry Division (Airmobile). Captain Orsini distinguished himself by exceptionally valorous actions on 15 December 1967 as commander of an infantry company conducting a search and destroy mission. His unit was moving toward a small village when it was subjected to intense automatic weapons and small arms fire from a well entrenched and numerically superior North Vietnamese Army force. Captain Orsini quickly moved forward to the point of heaviest contact and deployed his troops in defensive positions. When he was informed that the men of the company's right flank security element were wounded and unable to take cover, he fearlessly raced across one hundred meters of bullet-swept terrain to rescue the casualties. He reached them only to find that they had been killed. Returning to his command post, Captain Orsini learned that three soldiers of the point element were pinned down fifty meters to the front by the hostile fusillade. Braving a withering hail of enemy fire, he led two men to assist the beleaguered troops. One volunteer was killed and the other wounded by a North Vietnamese sniper, and Captain Orsini was forced to withdraw, carrying his wounded comrade back to the company' s defensive perimeter. He then called for armored personnel carriers to cover the withdrawal of the point men. When they arrived, he resumed his rescue efforts under their heavy suppressive fire. Although seriously wounded by the explosion of an enemy recoilless rifle round, Captain Orsini refused medical treatment and guided the beleaguered troops to safety. Captain Orsini's extraordinary heroism 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.
