The VS-2.2, VS-3.6 and SH-55 are Italian circular plastic cased anti-tank blast mines that use the VS-N series fuze.
It was produced by Valsella Meccanotecnica and Singapore, but production has ceased.
The mines are normally olive green or sand coloured and are circular.
The SH-55 is larger, and the circular main body is not as ribbed, it uses the same VS-N fuze as the other mines.
This secondary fuze well can easily be fitted with pull-fuze which functions as an anti-handling device.
