TMB and TMSB series mines
From Wikipedia, the free encyclopedia
The TMB-1,TMB-2, and TMSB were a round Soviet minimum metal anti-tank mines used during the Second World War. Both mines were similar in design, differing only in size, with the TMB-2 being the larger.
The mines bodies were constructed from asphalt impregnated cardboard with internal wooden slats for strengthening. A central glass pressure plug sat over an MV-5 pressure fuse. Downward force of about 26 pounds (115 newtons) causes the case to give way, triggering the mine.
The mine was normally employed in minefields mixed with metal cased anti-tank mines. The mines were also easy to fit with anti-handling devices.
