The HG 85 (Hand Granate M1985) is a round fragmentation hand grenade designed for the Swiss Armed Forces and still produced by RUAG Ammotec in Switzerland. HG 85 is the internal designation of the Swiss Army and replaces the HG 43 from WWII. On detonation the steel body, containing 155 g TNT, releases around 1800 fragments weighing on average 0.1 grams. UK grenade range safety data suggests the L109 – and by extension all live versions – may represent a danger at ranges up to 200 m. Intended for use mainly when fighting in built-up areas, trench clearing, and wood clearing, it is effective against unprotected personnel up to away, and protected personnel up to . Function The grenade is spherical with a bushing on the top threaded internally to accept the DM 82 CH fuze mechanism. Due to its specially constructed fuze and packaging, the grenade is considered very secure. It is designed to be effective against opponents wearing body armour, up to 20 layers of Kevlar and 1.6mm of titanium. A supplementary spring steel safety clip is clipped over the safety lever and bushing on top of the grenade preventing the safety lever from moving. Variants EUHG 85 In the Swiss Army there is a training hand grenade with nearly the same size TNT charge (120 vs. 155 g), but no shrapnel mantle. It is designated EUHG 85 for Explosiv-Übungshandgranate (explosive training hand granade). They are the same size, shape and weight, made up by adding iron powder, as the HG 85, and painted a coarse black. They are stamped "EXPLOSIV". They function in the same way as the HG 85. Due to the substantial explosive charge they are dangerous. The grenade housing, especially the fuze block, causes some fragmentation. Mark HG 85 Initial training in the Swiss Army is done with a Markier Handgranate 85. It is equal in size and shape to the HG 85, but contains no explosive charge. A small bang charge can be inserted by unscrewing the upper part (where the fuze and lever are). Releasing the lever ("spoon") activates a striker that fires the charge to produce a bang. This is used for training purposes especially when there is OpFor to simulate an explosion but not endanger anyone. The Mark HG 85 can be recovered and reloaded with another banger.
