OGPU Rifle Marksmanship Qualification Badge, 3rd Class (Late 1920s-Early 1930s)
Although in theory it could be issued to a Border Guard of State Security trooper of any rank, the majority of the recipients were probably officers. The last item to note is the orientation of the flag pole strings near the top being looped toward the center of the badge not just up and over the top of the flags like other early stamped examples.
