Original Item – Only One Available. This official breast badge was issued in the late 1980s to personnel of the 3rd Directorate "State Special Protection" under the Ministry of Public Security of the Mongolian People's Republic. During the socialist period, this service functioned as an elite internal security formation responsible for the protection of senior party and state leadership, as well as key state institutions.

In the framework of socialist Mongolia, the department was tasked with safeguarding high-ranking party and government officials, visiting delegations from friendly states, and strategically important government buildings, laboratories, and transport assets. Its duties included maintaining internal security, ensuring the uninterrupted functioning of vital state facilities, and preventing hostile or destabilizing actions against the socialist state. Badges from this service were issued strictly for official use and internal wear, making surviving late-1980s examples scarce and highly desirable among advanced collectors of Mongolian socialist-era security and internal affairs insignia.
