Mobilization Device (Miniature Medal Size)
Criteria: The bronze Mobilization Device or "M" Device is a decoration of the U.S. military that is worn as an attachment in the center of the U.S. Armed Forces Reserve Ribbon. It is awarded to personnel who have served in a recall to active duty from a reserve sector or National Guard.
One "M" device is awarded per operation, meaning that if a service member is recalled to the same operation more than once, they receive only one award. However, if a service member is recalled to separate operations, they receive the "M" Device for each operation. Multiple "M" Devices are replaced by a bronze award numeral depicting the number of awards received. Numerals are worn on the U.S. Armed Forces Ribbon centered and to the wearer's left of the original "M" Device.
Certain personnel who are authorized to wear the Hourglass Device may wear this on the Armed Forces Reserve Ribbon. It is centered to the wearer's right, with the "M" device in the center and a bronze award numeral on the left.
