RGD-33 grenade
The RGD-33 (Russian: Ручная Граната Дьяконова образца 33 года, romanized: Ruchnaya Granata Dyakonova obraztsa 33 goda, lit. 'Hand Grenade, Dyakonov design, pattern year 1933') is a Soviet dual use (offensive and defensive) stick grenade developed in 1933. Designed to replace the RG-14/30 which was an improved World War I vintage design, the RGD-33 proved to be overly complex to operate (especially in the hands of hastily trained conscripts), and too complex to easily produce during the Great Patriotic War.
