The Army Reserve Components Achievement Medal (ARCAM) is a Good Conduct Medal that is issued to a member of the United States Army Reserve. The ARCAM was originally required that a reservist completed four (4) years of honorable service as an active member of a reserve unit, however in 1995 that time requirement was lowered to three (3) years of qualified service. This change was not retroactive. Additional awards of this medal are represented by a bronze oak leaf cluster.
If a soldier begins service full time on federal service the become ineligible for the award and become eligible for the Army Good Conduct medal. The medal may be awarded to all enlisted soldiers, warrant and commissioned officers up to and including the grade of Colonel.
