The TM 65 (Telamiina 65) is a circular Finnish minimum metal anti-tank blast mine.
It is broadly based on the Russian TM-62 mine.
The mines body is made from a thin shell of fibreglass over a cast block of explosive, with a central fuze well that holds the pressure fuze.
However, if this is not installed, the mine will activate with a pressure of a few kg.
The mine also has a secondary fuze well on the side for the installation of anti-handling devices or daisy chaining several mines.
