In March, decades after their brave service, two San Antonio Army veterans will be awarded the Medal of Honor.

Sgt. Santiago Erevia and Master Sgt. Jose Rodela are two of three living recipients of the award recognizing bravery far exceeding the call of duty.

Both men will be decorated for action taken while serving in the Vietnam War.

On May 21, 1969, Erevia -- armed with two rifles and several grenades -- charged the enemy when his unit came under fire.

Erevia came home to work with the U.S. Postal Service. His son, Roland, served three tours in Iraq.

Rodela single-handedly knocked out a rocket launching site on Sept. 1, 1969. He did so despite shrapnel wounds in his head and back.

In 2002, Congress ordered a review of Jewish and Hispanic veterans' war records to find out who may have suffered discrimination.

They discovered potential African American discrimination as well.

President Obama will present the medal to both men in a White House ceremony on March 18.
