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. The mine is found in the Falkland Islands and the Western Sahara. An electronically fuzed version of this mine (the SB-81/AR-AN) was also produced which featured an integral anti-handling device plus self-destruct capability.
