The SB-81 is an Italian plastic cased minimum metal anti-tank blast mine dating from the early 1980s. The mine uses an air pressure based fuze, which gives it protection against overpressure and blast. It can therefore be regarded as a blast resistant mine. The mine can be scattered by hand or by mine laying systems.
