dependent on the weapon, firing range, and the course of fire. For example, to earn an Army Marksmanship Qualification Badge for Pistol at the Combat Pistol Qualification Course, one must have a combined hit count of 26 out of 30 for expert, 21 out of 30 for sharpshooter, and 16 out of 30 for marksman on firing tables one through five. Regardless of the soldier's overall score, everyone must have a minimum hit count of three out of five while wearing a gas mask for the chemical, biological, radiological, and nuclear firing table and two out of four while shooting at night for the night firing table. Each of these firing tables test the shooter on different aspects of combat pistol shooting (shooting from a concealed position, speed loading, shooting on the move, etc.) while engaging human silhouettes at varying distances within an allotted time. Army Marksmanship Qualification Badges are not permanent awards. When a soldier re-qualifies with their weapon at a different level, the soldier replaces their qualification badge with a new badge that reflects their current level. 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. Former Army qualification badges The Army began using marksmanship qualification badges in 1881 starting with the Marksman Button. That led to a variety of different U.S. Army branch specific marksmanship badges until 1897 when the Rifle Marksmanship Badges were implemented Army wide. The U.S. Army's Pistol Marksmanship Badges were implemented ten years later in 1907. Clasps were added to the Sharpshooter Marksmanship Badge and Expert Marksmanship Badge to indicate the year(s) a soldier requalified as a sharpshooter or expert. Up to three years were denoted on a single clasp. Upon earning the badge a fourth time, another clasp was added and that new clasp was used to denote up to three additional years of requalification; there was no limit to the number of clasps that could be hung from these badges. In 1915, the U.S. Army changed the design of the Expert Pistol Qualification Badge's pendant
