[3] Upon the outbreak of World War II, Garcia joined the United States Army at a recruiting station in his adopted hometown in November 1942.

[5] On November 27, 1944, García was an acting squad leader in his platoon, which found itself engaged in combat against the German troops in the vicinity of Grosshau, Germany.

Garcia's conspicuous heroism, his inspiring, courageous conduct, and his complete disregard for his personal safety wiped out two enemy emplacements and enabled his company to advance and secure its objective.

[1][6] On August 23, 1945, the President of the United States, Harry S. Truman presented Staff Sergeant García with the Medal of Honor at a ceremony in the White House.

[9] A month after he was awarded the Medal of Honor, Garcia was denied service at a restaurant located in a town just a few miles south of Houston because he was Hispanic.

It was only after national columnist Walter Winchell reported the incident and labeled Sugar Land the most racist city in America that charges were filed—against Garcia.

[10] On the evening of November 21, 1963, Marcario García greeted President John F. Kennedy at the door of the Rice Ballroom in Houston Texas.

The ballroom was filled with a diverse crowd of attendees that included Hispanic World War II veterans, Civil Rights advocates and future political activists.

In 1983 Vice President George Bush dedicated Houston's new Macario García Army Reserve Center, and in 1994 Macario Garcia Middle School of the Fort Bend Independent School District, in unincorporated Fort Bend County, Texas, near Sugar Land, was named in García's honor.
