The MINE (Micro-Injection Nuclear Entry) Charge is a variable setting explosive charge. It consists of a micro-fission bomb with a pump that controls the amount of radioactive material in the detonation chamber. There is such a small amount used that the explosive can blow through cloth and burn the surface underneath (albeit coating it with radiation), or a two meter thick bulkhead.
The charge can be shaped to fit a specific door's weak points, maximizing the effectiveness of the blast.
