Internal Workings
The bottle-shaped cast steel body has a central well for attaching the fuze assembly. The detonator is integrated with the mine body, and thus cannot be disarmed. The steel body contains the main charge and central propellant tube. The fuze assembly screws into the well at the top while the base consists of a heavy plug attached with shear screws. The mine body and fuze are olive green. Markings on the mine body are yellow, while those on the fuze are black. Initiating the fuze ignites a propellant charge in a central tube, which blows off the base to propel the mine body into the air. A tether wire fed from the base then initiates the detonator and main charge to shatter the steel body into fragments.

UPROM-1 tilt trigger is momentary push/pull activated, has high metal content.
