The anti-tank mine, designated Ba-III, was created by designers in Bulgaria in the early 1960s. It was designed for the needs of the Bulgarian Armed Forces, and after successful tests, it was adopted and mass production began at the Dunarit plant. It remained in service in Bulgaria until the late 1980s, but it is also known that these mines were supplied to Iraq.
Designed to disable enemy tracked and automotive equipment.
The mine is a flat, round box. Inside the case is an explosive charge, and a detonator is installed on top. Its case was made of bakelite and consisted of two parts glued together with a special glue. The lower part of the mine had a socket for an intermediate detonator at the bottom, closed with a screw plug. And the upper part of the mine had a thread for connecting a target pressure sensor and a socket for the detonator.
