• On March 18, 2014, President Barack Obama awarded 24 Army veterans with Medals of Honor in a single ceremony.
  • The unusual event honored veterans of World War II, the Vietnam War, and the Korean War who had previously been overlooked for the nation's highest military award for valor.
  • A 12-year congressional review of service records found dozens of awards had been overlooked or denied due to racial or ethnic discrimination.
  • Obama awarded 21 medals posthumously, and three to living recipients Melvin Morris, Jose Rodela, and Santiago Erevia.

On March 18, 2014, in one of the longest ceremonies of its kind, 24 Army veterans received the Medal of Honor for actions during their service in World War II, the Korean War, and the Vietnam War.

12 years earlier, Congress began a review of Jewish and Hispanic Americans' war records, finding that dozens had been overlooked or denied the nation's highest military award for valor due to discrimination.

"No nation is perfect," President Obama said at the ceremony. "But here in America, we confront our imperfections and face a sometimes painful past, including the truth that some of these soldiers fought and died for a country that did not always see them as equal."

Three living veterans were honored at the ceremony, and 21 were honored posthumously for their heroic actions. These are their stories.

With nothing but his M60 machine gun, Spc. Alvarado faced barrages of enemy gunfire, grenades, and satchel charges to provide cover as his unit aided another platoon in the jungles of Phuoc Long Province, Vietnam.

Steve Koppenhoefer, Alvarado's platoon leader, told Stars and Stripes the specialist was an extraordinary yet intimidating figure on the battlefield. He died from wounds sustained during the battle and was originally awarded the Distinguished Service Cross, the Army's second-highest award for bravery in combat.

Alvarado's award was upgraded to the Medal of Honor to reflect his sacrifice. Read the full citation.

While advancing through dense forest in Ap Tan Hoa, Vietnam, Staff Sgt. Conde-Falcon's unit encountered an enemy battalion command post.

"A platoon had stumbled into something unexpected, and the fight was hotter than Hades," Les Hays, a radio telephone operator who served with Conde-Falcon, told the Fayetteville Observer.

Ordered to clear the facility, Conde-Falcon charged ahead of his unit, dropping grenades as he jumped across rooftops. After returning to his unit, he then took a machine gun to assault another fortification. When he ran out of ammunition, he took up an M16 rifle and charged again. He was mortally wounded within 10 meters of his goal.

Remembered as a quiet hero, Erevia died at age 70 in 2016.

In Tam Ky, Vietnam in the spring of 1969, the man lauded as a humble servant crawled in plain view of enemy forces, gathering grenades and ammunition before taking an M16 rifle in each hand as he charged enemy forces to protect wounded comrades.

Erevia moved between enemy positions, holding live grenades before dropping them into bunkers. According to his citation, when he ran out of grenades he "silenced" the occupants of the final bunker "at point blank range."

Under cover of a thick fog in Changyong-ni, South Korea, enemy forces crept forward, closing in on 2nd Platoon, Company G, 7th Infantry Regiment, 3rd Infantry Division.

They sprang, launching a vicious assault on Pvt. Demensio Rivera and his unit. Rivera responded swiftly, using his rifle, a pistol, and grenades and even tangled with the enemy in a bout of hand-t0-hand combat.

Realizing he had just one grenade left, Rivera pulled the pin and waited until more enemies approached. He dropped the grenade at his own feet; the next morning, friendly forces found Rivera, miraculously still alive, surrounded by enemy dead.

Near Lure, France, during World War II, Germans abandoned their posts when they saw 1st Lt. Donald Schwab run up to one of their emplacements, knock a German in the head with the butt of his carbine, then drag him across a field swept with enemy fire to friendly lines.

Before conducting his one-man assault, 1st Lt. Schwab led his men through three separate attacks, pausing to take cover under intense barrages of German fire.

He moved along his own skirmish line, organizing evacuation of the wounded. Rallying his troops one last time, they came within 50 yards of German forces. From there, amid withering fire, he ran alone to a German position that caused several casualties to his own company. His citation reads:

"Silhouetted through the mist and rain by enemy flares, he charged to the German emplacement, ripped the half-cover off the hostile firing pit, struck the German gunner on the head with his carbine butt and dragged the German back through a hail of fire to friendly lines."

At this point, the Germans decided to withdraw, and Schwab was able to tend to his unit's casualties.
