Panssarimiina m/44
The Panssarimiina m/44 is a Finnish anti-tank blast mine. It entered service in 1944 and was used during the Second World War and Continuation War. The mine used a wooden case, consisting of an upper box containing the main charge and a downward facing fuze, this was placed into a sturdy wooden tray, larger than the box. Enough pressure on the upper box resulted in the upper box collapsing into the lower tray and triggering the detonator.
