Medal of Honor recipient Marine Cpl. Kyle Carpenter paid a visit to the Pentagon today to visit Sgt. Maj. Ronald L. Green, the highest ranking enlisted Marine and a senior advisor to the commandant of the Marine Corps.

But when Carpenter entered the sergeant major’s office, Green wasn’t there. Sporting casual shorts and a “Semper Fi” T-shirt, Carpenter took advantage of his absence and stole a moment behind his desk, Carpenter’s Instagram shows:

Carpenter enlisted in the Marine Corps in 2009 before deploying to Afghanistan in 2010. His citation states he was serving as a rifleman in Helmand province, Afghanistan, in November 2010 when enemy insurgents attacked his platoon with hand grenades while Carpenter and a fellow Marine manned a rooftop.
