Answer:

What is Joint Service Achievement Medal mean?

The Achievement Medal is a military decoration of the United States Armed Forces. The Achievement Medal was first proposed as a means to recognize outstanding achievement or meritorious service of military personnel who were not eligible to receive the higher Commendation Medal or the Meritorious Service Medal.

Each military service issues its own version of the Achievement Medal, with a fifth version authorized by the U.S. Department of Defense for joint military activity. The Achievement Medal is awarded for outstanding achievement or meritorious service not of a nature that would otherwise warrant awarding the Commendation Medal. Award authority rests with local commanders, granting a broad discretion of when and for what action the Achievement Medal may be awarded.
