Korean War
The Korean war saw more than 240,000 Army Reserve Soldiers called to active duty, reflecting the Army’s reliance on the reserve component.

Representing more than 70 units, Army Reserve Warrior-Citizens received nearly 10 percent of top combat decorations, including seven Medals of Honor. The types of units that served in Korea included quartermaster,engineer, transportation, military intelligence, ordnance and artillery. During the Korean War, Congress began making significant changes in the structure and role of the Army Reserve. On July 9, 1952, these changes were implemented, transforming the Organized Reserve into the United States Army Reserve.

Today: Enabling the Total Force

The Army Reserve continues to evolve to meet the needs of the Nation. To prepare for future challenges, the Army Reserve plays an integral role in the leaner, smarter, more lethal and flexible Army of the 21st century.

With a substantial portion of the Army’s strategic and operational “enablers”—specialized fields that complement or enable the Total Force—the Army Reserve comprises nearly 20 percent of all the Army’s organized units, half its combat support, a quarter of its mobilization base expansion capability and some 75 percent of key capabilities, such as medical, logistics,transportation, full-spectrum engineering, and civil affairs.

Following the war, he enlisted in the Organized Reserve and was recalled to active duty following the start of the Korean War. He was awarded the Medal of Honor for his actions on April 24-25, 1951, but his award was kept secret for his safety until after his repatriation in August 1953.
