The Soviet F1 hand grenade (Russian: Фугасный > Fugasnyy 1, "Explosive, Type #1"), is an anti-personnel fragmentation defensive grenade. It is based on the French F1 grenade and contains a 60-gram explosive charge (TNT). The total weight of the grenade with the fuze is about 600 grams.

Due to its shape and its yellow-green color, it is nicknamed the limonka (fem. "lemon"). It is also nicknamed Efka (Russian: Эфка) for the letter F.[3] It is similar to the American Mk 2 "pineapple grenade", which was also ultimately modeled on the French F1.

The Soviet RG-42 (Ручная Граната образца 42 года > Ruchnaya Granata obraztsa 42 goda, "Hand Grenade pattern of [19]42 year") was a fragmentation grenade designed by S.G. Korshunov[1].

It was originally introduced during World War II from 1942 onwards as an emergency measure to replace the complex RGD-33 grenade. It continued in use with the USSR and its Warsaw Pact allies in the post-war period until replaced in 1954 by the RGD-5 grenade. Stockpiles were held for emergency or reserve issue, military aid, or foreign sales. They were eventually destroyed in the 1980s due to the TNT filling degrading and becoming unsafe.

Unlike the RGD-33, the RG-42's components were simple to produce and assemble. Only the fuze required specialized manufacture and the parts could be easily assembled by hand by cottage labor. Partisans often made copies of the simple design when out of contact.

It contained about 200 grams of explosive charge (TNT) in a cylindrical stamped-metal can. It used the 3.2 to 4 second UZRGM fuse, also used in the RGD-5, RG-41, and F1 grenades.

The grenade could be thrown about 35–40 meters and has an effective blast radius of around 10 meters.

The total weight of the grenade with the fuse was 420 grams[1].

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

The grenade is egg-shaped with no external ribbing, except for a lateral ridge where the two halves of the grenade join. It weighs 310 grams (11 oz). It is 117 millimetres (4.6 in) in length and 58 millimetres (2.3 in) in diameter. The surface has a few small dimples on it with a green or olive drab paint-scheme.

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 fatality radius of around 3 metres (9.8 ft)[1] and a wounding radius of 25 metres (82 ft).[2][3] Typically, the RGD-5 uses the 3.2 to 4.2 second delay UZRG, UZRGM, or UZRGM-2 fuze, a universal Russian type that is also used in the RG-41, RG-42, and F1 grenades.[4] The RGD-5 can be thrown about 35 to 45 metres (115 to 148 ft) by the average male soldier and, when throwing, the grenade will make a loud "crack" sound as its spoon falls out activating the fuze, cooking off the grenade.

This grenade is still manufactured in Russia with copies produced in Bulgaria, China (as the Type 59) and Georgia. Many millions of RGD-5s and its clones have been manufactured over the years and, although not as advanced as more modern grenades that are specifically designed to penetrate CRISAT standard body armour, the RGD-5 is still an effective and inexpensive weapon. A single RGD-5 grenade costs around $5 US, making it highly affordable during a major conflict when many grenades are sought.

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.
