U.S. Army Expert Marksmanship Qualification Badge. USA.

Three types of Marksmanship Qualification Badges exist: Expert, Sharpshooter and Marksman.
The U.S. Army awards Army Marksmanship Qualification Badges to its soldiers, U.S. Army uniformed civilian guards, and foreign military personnel, while the CMP awards these same badges to U.S. civilians who qualify at three different qualification levels (highest to lowest): expert, sharpshooter, and marksman.
Suspended from the badge are Army Weapon Qualification Clasps that indicate the type of weapon the individual has qualified to use.
The following list of Army Weapon Qualification Clasps are currently authorized: Rifle, Pistol, AA Artillery, Auto Rifle, Machinegun, Field Artillery, Tank Weapons, Flamethrower, Submachine Gun, Rocket Launcher, Grenade, Carbine, Recoilless Rifle, Mortar, Bayonet, Small Bore Rifle, Small Bore Pistol, Missile, Aero weapons.
Only three Army Marksmanship Qualification Badges are authorized for wear on U.S. Army service uniforms and each may have no more than three Army Weapon Qualification Clasps.
Although these badges are awarded to both officers and enlisted soldiers alike, as a matter of U.S. Army tradition, only non-commissioned officers and enlisted soldiers are expected to wear these badges on their service uniforms in most units, although policy is set by the commander of each unit.
