Andreotta was posthumously awarded the Soldier's Medal in 1998 for his bravery in stopping the My Lai Massacre, along with Lawrence Colburn and Hugh Thompson, Jr.. Since his mother was in ill health at the time, she accepted his award at her home at a later date. "It was the ability to do the right thing even at the risk of their personal safety that guided these soldiers to do what they did," then-Major General Michael Ackerman said at the ceremony. The three "set the standard for all soldiers to follow." Additionally on March 10, 1998, Senator Max Cleland (D-GA) entered a tribute to Thompson, Colburn and Andreotta into the record of the U.S. Senate. Cleland said the three men were, "true examples of American patriotism at its finest."
