ŠKOLSKA TENKOVSKA MINA ANTIMAGNETNA-3
This mine is a classroom version of TMA-3, which is used for educating engineers and pyrotechnics in Yugoslav people's army military schools.
This inert mine is made of heavy olive-drab rubber, and it has canvas carrying strap on the side.
It has four cavities in its body: three on the upper side to fit aluminium cans which have the same dimensions as the tetryl boosters on the "live" TMA-3.
These aluminium cans have bakelite school fuzes or plastic protective caps on their tops. From the bottom side, ŠTMA-3 has one more hole 10 mm in diameter for screwing school boobytrap pressure-release fuze.
ŠTMA-3 has the same dimensions,weight and color just like the real TMA-3.
