The first and third devices aren't exactly medals, but are meant to be worn on the lapel of the service coat. The second decoration is an Army Meritorious Unit Commendation (in the same vein, but of a lesser degree than a Presidential Unit Citation) The last decoration is a "sharpshooter" level Army marksmanship qualification badge with the "RIFLE" weapon qualification clasp, indicating satisfactory completion of qualification courses with the assigned weapon.
