The MON-50 () is a Soviet rectangular, slightly concave, plastic bodied, directional type of anti-personnel mine designed to wound or kill by explosive fragmentation. It first entered service in 1965 and is a copy of the American M18 Claymore with a few differences. Its name is derived from Russian мина осколочная направленного (mina oskolochnaya napravlennogo), "directional fragmentation mine". Design Based on the American M18A1 Claymore, the MON-50 has folding scissor type legs for supporting and aiming, but it also has an attachment point on the bottom for connecting a special clamp/spike which can be attached to wood, metal etc. It has a peep sight centered on the top which is flanked by two detonator cavities. The mine contains 700 g of RDX (PVV-5A) to propel approximately 540 or 485 fragments to a lethal range of 50 meters in a 54° arc (spread of 45 meters at 50 meter range). The fragments can be steel balls (540) or short steel rods (485) depending on the variant. The MON-50 is usually command actuated using a PN manual inductor and an EDP-R electric detonator. It can also be actuated by a variety of booby trap (BT) switches including the MUV series pull; the MVE-72 electric breakwire; or the VP13 seismic controller. The MON-50 will usually be mounted above ground level on the surface or up in trees to give the greatest dispersion of fragments. It is waterproof and will function effectively from +50 to −50 °C (it can be buried in snow as long as the pack in front of the mine does not exceed 10 cm; any more will greatly reduce its effectiveness). The mine can be located visually or with metal detectors under most field conditions. Depending on its actuation method, the MON-50 may be resistant to blast overpressure from explosive breaching systems like the Giant Viper and M58 MICLIC. The MON-50 is currently manufactured in Russia and also manufactured for export in Bulgaria. The MON-50 is widely used in many parts of the world. It comes in a two pouch cloth bandolier which holds all the components for securing and command actuating the mine. It may also come packed in a VKPM-2 set which contains four mines complete with miscellaneous fuzes, control panel and wire.
