The coins, that were originally offered to select military personnel, have recently been made available to the public sector. Besides challenging, Challenge Coins were also used as awards and rewards for those who performed outstanding service. Originally used to build morale among the troops, it is believed that the tradition started during the Vietnam War when Challenge Coins were first given to those who served in the Special Forces units. The tradition spread and in the early 1980's was welcomed by the 75th Ranger Regiment. As officers began to be reassigned with their careers progressing, they were awarded unit coins for acts that were worthy of recognition. Challenge Coins were uncommon until the Gulf War in 1990-1991, and have grown tremendously in popularity. Challenge Coins were also presented to the gunners after they graduated from Air Force Technical Training School honoring them with entry into the prestigious, "Gunners Association." When bombers were used, a Challenge Coin was presented as a show of courage and strength, which reflected the official mascot of the gunner, the Bulldog.
