A Marine truck mechanic received a medal typically awarded to more senior service members for saving the Defense Department more than $140 million through work he began as a teenage lance corporal. Cpl. Gage Barbieri, now 21, received the Meritorious Service Medal on Friday from Col. Damon Burrows, commanding officer of 2nd Marine Division’s Headquarters Battalion. Barbieri is only the second Marine corporal to receive the Meritorious Service Medal since at least 2008, Burrows wrote on LinkedIn
