How army soldiers use a metal?

Medals in the military are awards. They wear them on their uniforms or display them on the walls at home. Certain military awards also allow some specific privileges for the men who won them in battle. Up until the Vietnam War, the son of a Medal of Honor winner was automatically qualified (with all other standards being met) to enter the US Military Academy at West Point. Medals also helped servicemen get promoted to higher ranks when other standards were met.

US Airmen, US Coast Guardsmen, US Marines, US Sailors, and US Soldiers are all elgible to receive military awards (medals).
