As one of the three military departments operated by the U.S. Department of Defense, the Army’s main function is to fight and contribute to the victories of our nation’s wars. It’s quick and continuous land control, which spans across all combat areas, is the heart of the Army’s operations. Being able to successfully organize, equip and train its forces to achieve this goal is a feat often recognized using Army challenge coins. Challenge coins made to celebrate the completion of training, a change in rank or receipt of special honors and awards are some of U.S. DOD Coins most common military coin requests. We have also seen Army coins used to mark specific events or periods of time and make remembrances of companies, units and platoons something tangible.
