Military commanders often give pocket-size medallions, called challenge coins, to service members as a mark of camaraderie. A commander's unique coin — often copper, bronze or nickel — carries symbols and mottos denoting the unit or office.
 
These special SOF Foundation coins show the SOF Foundation logo on one side and the logos of the USSOCOM (US Marice Corps), Navy Special Operations, Army Special Operations, Air Force Special Operations and Joint Special Operations Command.
