1LT Samuel Streit Coursen
Awarded for actions during the Korean War
The President of the United States of America, in the name of Congress, takes pride in presenting the Medal of Honor (Posthumously) to First Lieutenant (Infantry) Samuel Streit Coursen, United States Army, for conspicuous gallantry and intrepidity above and beyond the call of duty while serving with Company C, 1st Battalion, 5th Cavalry Regiment, 1st Cavalry Division, in action against enemy aggressor forces at Kaesong, Korea, on 12 October 1950.
While Company C was attacking Hill 174 under heavy enemy small-arms fire, First Lieutenant Coursen's platoon received enemy fire from close range. The platoon returned the fire and continued to advance. During this phase one his men moved into a well-camouflaged emplacement, which was thought to be unoccupied, and was wounded by the enemy who were hidden within the emplacement.
Seeing the soldier in difficulty he rushed to the man's aid and, without regard for his personal safety, engaged the enemy in hand-to-hand combat in an effort to protect his wounded comrade until he himself was killed. When his body was recovered after the battle seven enemy dead were found in the emplacement. As the result of First Lieutenant Coursen's violent struggle several of the enemies' heads had been crushed with his rifle. His aggressive and intrepid actions saved the life of the wounded man, eliminated the main position of the enemy roadblock, and greatly inspired the men in his command.
First Lieutenant Coursen's extraordinary heroism and intrepidity reflect the highest credit on himself and are in keeping with the honored traditions of the military service.

The President of the United States of America, in the name of Congress, takes pride in presenting the Medal of Honor (Posthumously) to First Lieutenant (Infantry) Robert Milton McGovern, United States Army, for conspicuous gallantry and intrepidity at the risk of life above and beyond the call of duty while serving with Company A, 5th Cavalry Regiment, 1st Cavalry Division, in action against enemy aggressor forces at Kamyangjan-ni, Korea, on 30 January 1951.
As First Lieutenant McGovern led his platoon up a slope to engage hostile troops emplaced in bunker-type pillboxes with connecting trenches, the unit came under heavy machinegun and rifle fire from the crest of the hill, approximately 75 yards distant. Despite a wound sustained in this initial burst of withering fire, First Lieutenant McGovern, assured the men of his ability to continue on and urged them forward. Forging up the rocky incline, he fearlessly led the platoon to within several yards of its objective when the ruthless foe threw and rolled a vicious barrage of hand grenades on the group and halted the advance. Enemy fire increased in volume and intensity and First Lieutenant McGovern realizing that casualties were rapidly increasing and the morale of his men badly shaken, hurled back several grenades before they exploded.
Then, disregarding his painful wound and weakened condition he charged a machinegun emplacement which was raking his position with flanking fire. When he was within ten yards of the position a burst of fire ripped the carbine from his hands, but, undaunted, he continued his lone-man assault and, firing his pistol and throwing grenades, killed seven hostile soldiers before falling mortally wounded in front of the gun he had silenced.
First Lieutenant McGovern's incredible display of valor imbued his men with indomitable resolution to avenge his death. Fixing bayonets and throwing grenades, they charged with such ferocity that hostile positions were overrun and the enemy routed from the hill.
The inspirational leadership, unflinching courage, and intrepid actions of First Lieutenant McGovern reflected utmost glory on himself and the honored tradition of the military services.

COLONEL LLOYD L. (SCOOTER) BURKE, (then First Lieutenant) U.S. Army, Company G, 5th Cavalry Regiment, 1st Cavalry Division, Near Chong-dong, Korea, 28 October 1951, distinguished himself by conspicuous gallantry and outstanding courage above and beyond the call of duty in action against the enemy. Intense enemy fire had pinned down leading elements of his company committed to secure commanding ground when 1st Lt. Burke left the command post to rally and urge the men to follow him toward 3 bunkers impeding the advance. Dashing to an exposed vantage point he threw several grenades at the bunkers, then, returning for an M1 rifle and adapter, he made a lone assault, wiping out the position and killing the crew. Closing on the center bunker he lobbed grenades through the opening and, with his pistol, killed 3 of its occupants attempting to surround him. Ordering his men forward he charged the third emplacement, catching several grenades in midar and hurling them back at the enemy. Inspired by his display of valor his men stormed forward, overran the hostile position, but were again pinned down by increased fire. Securing a light machine gun and 3 boxes of ammunition, 1st Lt. Burke dashed through the impact area to an open knoll, set up his gun and poured a crippling fire into the ranks of the enemy, killing approximately 75. Although wounded, he ordered more ammunition, reloading and destroying 2 mortar emplacements and a machine gun position with his accurate fire. Cradling the weapon in his arms he then led his men forward, killing some 25 more of the retreating enemy and securing the objective. 1st Lt. Burke's heroic action and daring exploits inspired his small force of 35 troops. His unflinching courage and outstanding leadership reflect the highest credit upon himself, the infantry, and the U.S. Army.

LTC Bruce Crandall
On February 26, 2007, Crandall was awarded the Medal of Honor by President George Bush for his actions at the Battle of la Drang.
For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty: Major Bruce P. Crandall distinguished himself by extraordinary heroism as a Flight Commander in the Republic of Vietnam, while serving with Company A, 229th Assault Helicopter Battalion, 1st Cavalry Division (Airmobile). On 14 November 1965, his flight of sixteen helicopters was lifting troops for a search and destroy mission from Plei Me, Vietnam, to Landing Zone X-Ray in the Ia Drang Valley. On the fourth troop lift, the airlift began to take enemy fire, and by the time the aircraft had refueled and returned for the next troop lift, the enemy had Landing Zone X-Ray targeted. As Major Crandall and the first eight helicopters landed to discharge troops on his fifth troop lift, his unarmed helicopter came under such intense enemy fire that the ground commander ordered the second flight of eight aircraft to abort their mission. As Major Crandall flew back to Plei Me, his base of operations, he determined that the ground commander of the besieged infantry battalion desperately needed more ammunition. Major Crandall then decided to adjust his base of operations to Artillery Firebase Falcon in order to shorten the flight distance to deliver ammunition and evacuate wounded soldiers. While medical evacuation was not his mission, he immediately sought volunteers and with complete disregard for his own personal safety, led the two aircraft to Landing Zone X-Ray. Despite the fact that the landing zone was still under relentless enemy fire, Major Crandall landed and proceeded to supervise the loading of seriously wounded soldiers aboard his aircraft. Major Crandall's voluntary decision to land under the most extreme fire instilled in the other pilots the will and spirit to continue to land their own aircraft, and in the ground forces the realization that they would be resupplied and that friendly wounded would be promptly evacuated. This greatly enhanced morale and the will to fight at a critical time. After his first medical evacuation, Major Crandall continued to fly into and out of the landing zone throughout the day and into the evening. That day he completed a total of 22 flights, most under intense enemy fire, retiring from the battlefield only after all possible service had been rendered to the Infantry battalion. His actions provided critical resupply of ammunition and evacuation of the wounded. Major Crandall's daring acts of bravery and courage in the face of an overwhelming and determined enemy are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.

SGT John Noble Holcomb
Sergeant Holcomb's 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. Sgt. Holcomb distinguished himself while serving as a squad leader in Company D during a combat assault mission. Sgt. Holcomb's company assault had landed by helicopter and deployed into a hasty defensive position to organize for a reconnaissance-in-force mission when it was attacked from 3 sides by an estimated battalion-size enemy force. Sgt. Holcomb's squad was directly in the path of the main enemy attack. With complete disregard for the heavy fire, Sgt. Holcomb moved among his men giving encouragement and directing fire on the assaulting enemy. When his machine gunner was knocked out, Sgt. Holcomb seized the weapon, ran to a forward edge of the position, and placed withering fire on the enemy. His gallant actions caused the enemy to withdraw. Sgt. Holcomb treated and carried his wounded to a position of safety and reorganized his defensive sector despite a raging grass fire ignited by the incoming enemy mortar and rocket rounds. When the enemy assaulted the position a second time, Sgt. Holcomb again manned the forward machine gun, devastating the enemy attack and forcing the enemy to again break contact and withdraw. During the enemy withdrawal an enemy rocket hit Sgt. Holcomb's position, destroying his machine gun and severely wounding him. Despite his painful wounds, Sgt. Holcomb crawled through the grass fire and exploding mortar and rocket rounds to move the members of his squad, everyone of whom had been wounded, to more secure positions. Although grievously wounded and sustained solely by his indomitable will and courage, Sgt. Holcomb as the last surviving leader of his platoon organized his men to repel the enemy, crawled to the platoon radio and reported the third enemy assault on his position. His report brought friendly supporting fires on the charging enemy and broke the enemy attack. Sgt. Holcomb's inspiring leadership, fighting spirit, in action at the cost of his life were in keeping with the highest traditions of the military service and reflect great credit on himself, his unit, and the U.S. Army.

SP 4 John Baca
Medal of Honor Official Citation reads:
For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Sp4c. Baca, Company D, distinguished himself while serving on a recoilless rifle team during a night ambush mission. A platoon from his company was sent to investigate the detonation of an automatic ambush device forward of his unit's main position and soon came under intense enemy fire from concealed positions along the trail. Hearing the heavy firing from the platoon position and realizing that his recoilless rifle team could assist the members of the besieged patrol, Sp4c. Baca led his team through the hail of enemy fire to a firing position within the patrol's defensive perimeter. As they prepared to engage the enemy, a fragmentation grenade was thrown into the midst of the patrol. Fully aware of the danger to his comrades, Sp4c. Baca unhesitatingly, and with complete disregard for his own safety, covered the grenade with his steel helmet and fell on it as the grenade exploded, thereby absorbing the lethal fragments and concussion with his body. His gallant action and total disregard for his personal well-being directly saved 8 men from certain serious injury or death. The extraordinary courage and selflessness displayed by Sp4c. Baca, at the risk of his life, are in the highest traditions of the military service and reflect great credit on him, his unit, and the U.S. Army.

CW3 Cornell C. Chao
The President of the United States takes pride in presenting the Silver Star Medal (Posthumously) to Cornell C. Chao, Chief Warrant Officer 3, U.S. Army, for conspicuous gallantry and intrepidity in action against the enemy while serving as Pilot of an AH-64D Longbow Apache Helicopter with the 4th Battalion, 227th Aviation Regiment, 1st Air Cavalry Brigade, 1st Cavalry Division, during combat operations in support of Operation IRAQI FREEDOM, on 28 January 2007, near An Najaf, Iraq. On that date, Chief Warrant Officer Three Chao was dispatched to the city of An Najaf to assist and support coalition troops who had come in contact with enemy forces. Arriving support aircraft was attacked with heavy machine gun fire and rocket propelled grenades and Chief Warrant Officer Three Chao placed his helicopter in the direct line of enemy fire so that another air crew that was under attack could maneuver out of danger. Over the next fifteen minutes he bravely flew in the face of intense enemy fire to support the coalition ground forces until his aircraft was struck and crashed, killing Chief Warrant Officer Three Chao.
On 22 April enemy activity across the whole front suddenly increased and the U.N. advance halted abruptly. The expected spring offensive was at hand.
Following a four-hour artillery bombardment, three Chinese Communist armies attacked the U.N. line in the evening hours of 22 April. The main attack was against the U.S. I and IX Corps in the Seoul sector, coupled with a secondary thrust in the central Yonch'on-Hwach'on area and a p w h in the seat near Inje. U.N. lines held firm except in the IX Corps central sector, where ROK units were forced back in confusion. With the line broken, Van Fleet ordered the I and IX Corps to withdraw through a series of delaying positions to Line KANSAS, thus giving up the ground gained in recent U.N. offensives. When the enemy cut the Seoul-Kaesong highway on 26 April, Van Fleet withdrew the IX Corps back to the Hongch'on River.
Meanwhile, in the I Corps area, the enemy crossed the Imjin River on 22 April and drove the ROK unite south of the KANSAS Line on the 23d. On 27 April the enemy outflanked Uijongbu, forcing U.N. units to pulls back to within four miles of Seoul, and also made an unsuccessful attempt to outflank the city to the east. On the east-central front North Koreans captured Inje. By 29 April, however, their drive had been halted. On this date Van Fleet established a new line, designated NONAME-LINE, extending from north of Seoul to Sabangue and thence northeast across the 38th parallel to Taepo-ri on the east coast. Because the major enemy attack had been in the west, Van Fleet reshuffled his units to put more American divisions there. By the end of April, U.N. forces had stopped the enemy short of Seoul and the Han and held a strong, continuous defense line.
As the enemy withdrew to recoup losses, Van Fleet improved his defenses on NO-NAME-LINE and planned an offensive to carry the Eighth Army back to Line KANSAS; but signs of another impending enemy attack led him to postpone it.
On the night of 15-16 May an estimated 21 Chinese divisions, flanked by 3 North Korean divisions in the west and 6 in the east, struck in the central sector against the U.S. X and the ROK III Corps in the Naep'yong-ni-No-dong area. ROK units were again forced back by the swarming columns of Chinese and North Koreans. Once more Van Fleet reshuffled his units, moved in reserves, and laid down a tremendous curtain of artillery fire which exacted heavy casualties and stopped the enemy offensive.
On 17 May the enemy struck down the Pukhan River toward the Han in the western sector, against the I and IX Corps, with a force of about 250,000 men. This attack was also contained after three days of violent action. By 20 May U.N. troops brought the enemy to a standstill, having thus stopped two major offensives in two months.
Van Fleet decided to renew the offensive, so as to give the enemy no chance to gather himself for another counterstrike. On 18 May he opened a series of local attacks. Once more enemy forces pulled back and U.N. forces moved forward against light resistance. Within a few days the I Corps reached the Imjin River north of Munsan-ni and entered Uijongbu and Sinp'al-li. The IX Corps pushed toward Kap'yong, drove the enemy across the Hanch'on River, and moved toward the Hwach'on Reservoir. In the X Corps area the 1st Marine Division attacked Yanggu on 24 May. The 187th RCT headed for Inje, which it captured on the 27th. The Marines were pushing toward the Hwach' on Reservoir and Yanggu. The 7th Division of the I Corps took Hwach'on. By 31 May the U.N. forces scored a significant advance which brought them just about back to the KANSAS Line, and South Korea was virtually cleared of the enemy.
At this point the Joint Chiefs of Staff prescribed that the Eighth Army was not to go beyond the general vicinity of Line KANSAS. The only tactical operations permitted were those necessary to protect itself, to maintain contact, and to harass the enemy. This was the basic pattern of U.N. military operations which was to be followed throughout the remainder of the war.
On 1 June, therefore, Van Fleet ordered his reserve forces to strengthen KANSAS so as to make it virtually impregnable. Meanwhile the I and IX Corps were to continue Operation PILEDRIVER toward Line WYOMING (the bulge north of KANSAS that ran from the Imjin River to points just south of Ch'orwon and Kumhwa and thence southeast). Ch'orwon and Kumhwa were captured on 11 June. Two tank-infantry task fences reached P'yongyang, the northern tip of the Iron Triangle, on 13 June and found it deserted. The dominating high ground north of the city was held by the enemy, however, and U.N. forces withdrew. The Chinese reoccupied P'yongyang on 17 June. Meanwhile the X Corps on the east-central front pushed through mountains toward its sector of the KANSAS Line, which extended over a series of ridges from the Hwach'on Reservoir northeastward to the lower lip of the "Punchbowl," an aptly named circular depression north of Inje. Thus by mid-June the Eighth Army had attained the principal terrain objectives of Operation PILEDRIVER. Action for the rest of the month was confined to developing the KANSAS and WYOMING Lines, and to patrolling and local clashes.
