Polish RPG-43 INERT Training Grenade.
The RPG-43 (ruchnaya protivotankovaya granata obraztca 1943 goda, meaning hand-held anti-tank grenade) was a high-explosive anti-tank (HEAT) shaped charge hand grenade used by the Soviet Union during World War II. It entered service in 1943, replacing the earlier models RPG-40 and RPG-41; the RPG-40 used a simpler high explosive (HE) warhead. The RPG-43 had a penetration of around 75 millimetres (3.0 in) of rolled homogeneous armour at a 90 degree angle.
The RPG-43 externally was shaped like an oversized stick grenade with a 95 mm HEAT warhead on the end. It weighed 1.247 kilograms (2.75 lb) of which 0.612 kilograms (1.35 lb) was high explosive. When thrown, a cylindrical metal cone was released from the rear of the grenade and held by fabric strips to stabilise flight and increase the likelihood of a 90 degree hit. Its range was limited by how far a user could throw it,
