The MIACAH F1 (L14A1 in British service) is a French off-route anti-tank landmine. It uses a large Misznay Schardin effect warhead to project a powerful self forging fragment capable of penetrating 70 millimetres of armour at a range of 40 metres.
The mine consists of a horizontal cylindrical main body with a large inset plate in the front. The detonator protrudes from the centre of the front plate. The main body is supported on two arms which are attached to a circular base with three stakes. The mine can be triggered by a 50-metre breakwire, command or electronically triggered by an external sensor.
The mine is no longer in production, and has been withdrawn from service from the French and British armies. The mine has been reported in Iraq.
