RGD-33 grenade

The Soviet RGD-33 is an anti-personnel fragmentation stick grenade developed in 1933. It was designed to replace the ageing Model 1914 grenade and was used during World War II.

Before use, a locking catch on the handle must be released and a fuse, lasting an average of 4 seconds, was inserted into the top of the can. A good throw could send the grenade 30 to 40 metres. Upon detonation the shells fragment in rectangular, thin fragments, which, along with the casing and detonator fragments, decelerate rapidly in air. Due to the fragments' rapid loss of velocity, the kill radius is small, making this grenade an "offensive" type. The fragmentation kill radius was approximately 15 metres with the sleeve and 10 metres without. As with most grenades of this era, there is potential for large fragment projection a great distance further than the throw.

The grenade was unusual but not unique, in that it had an optional "jacket" – a thick metal fragmentation sleeve weighing an average of 270 grams. When fitted over the grenade the sleeve improves the kill radius by producing a number of diamond-shaped, heavier fragments. With the jacket installed the grenade was said to be in "defensive" mode.

RGD-5

The RGD-5 (Ruchnaya Granata Distantsionnaya) English "Distance Hand Grenade" or "Time-delayed Hand Grenade", is a post World War II Soviet anti-personnel fragmentation grenade, designed in the early 1950s. RGD-5 was accepted to service in 1954, and is still in service with many of Russia's former client states and has been supplied to Iraq as well as other Arab nations.

Composition

The grenade contains a 110-gram (3.9 oz) charge of TNT with an internal fragmentation liner that produces around 350 fragments and has a lethality radius of 25 metres (82 ft). The weight of the grenade with the fuze fitted is 310 grams (11 oz). Typically, the RGD-5 uses the 3.2 to 4 second delay UZRGM fuze, a universal Russian type which is also used in the RG-41, RG-42, and F1 grenades. The RGD-5 may also be fitted with the more modern DVM-78 fuze, or variants of the UZRGM with delays of between zero (i.e. instantaneous for use in booby traps) and 13 seconds. It is also possible to screw an MUV booby-trap firing device into the fuze well.
