The Commendation Medal is a mid-level United States military award/ decoration which is presented for sustained acts of heroism or meritorious service. For valorous actions in direct contact with an enemy force, but of a lesser degree than required for the award of the Bronze Star, the Valor device ("V" device) may be authorized as an attachment to the decoration. Each branch of the United States Armed Forces issues its own version of the Commendation Medal, with a fifth version existing for acts of joint military service performed under the Department of Defense.
