The AUPS is an Italian Bakelite-cased AP blast mine that can have a metal jacket and tripwire fuze added to turn it into a stake mounted fragmentation mine. It is known to have been used extensively in Northern Mozambique.
Its main charge is 115g TNT/RDX (Composition B).
Without the fragmentation casing:
Height 36mm
Diameter 102mm
In blast mode, the mine is very hard to detect.
