badges are awarded in five to six grades (highest to lowest): distinguished expert, expert, sharpshooter, marksman first-class (Winchester/NRA Marksmanship Qualification Program only), marksman, and pro-marksman. U.S. law enforcement marksmanship qualification badges tend to follow NRA guidelines for marksmanship qualification badges or have their own criteria and badge structure. The NRA and the U.S. National Guard marksmanship competition badges are only awarded at one grade with the exception of the NRA's Law Enforcement Distinguished Program, which awards a Law Enforcement Excellence-in-Competition Badge for those officers who earn their first points towards one of the law enforcement distinguished badges. Marksmanship qualification badges Starting in the late 19th century, the U.S. Army began awarding marksmanship qualification badges to its soldiers who met specific weapon qualification standards. In the early 20th century, the U.S. Marine Corps and U.S. Navy began awarding marksmanship qualification badges as well. The Marine Corps began by awarding Army Marksmanship Qualification Badges but eventually developed its own badge design, based on the original Army designs from the early 1900s. The Navy developed its own marksmanship qualification badge but retired it after only ten years in lieu of awarding marksmanship ribbons and medals. For U.S. civilians, the Office of the Director of Civilian Marksmanship—now known as the Corporation for the Promotion of Rifle Practice and Firearm Safety (CPRPFS)—and the NRA began promoting civilian marksmanship in 1903. The CPRPFS's CMP awards Army Marksmanship Qualification Badges to civilians who meet U.S. Army weapon qualification standards as well as its own badges to youth for air rifle marksmanship. The NRA began awarding its own marksmanship qualification badges to civilians in 1918 and today has two primary marksmanship proficiency programs, the Winchester/NRA Marksmanship Qualification Program and the Explorer Service Handgun Qualification Program. Additionally, the NRA supports numerous other firearm proficiency programs throughout the United States, such as those found within various U.S. law enforcement organizations. U.S. Army 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 under U.S. Army Pamphlet 670-1: The level at which one qualifies is
