HomeGRENADESSOVIET & BALKANCroatia

At the beginning of war in former-Yugoslavia in 1991, these grenades were the first improvisations made by Croatian army.
They were made at the first line of the battlefield using available materials and explosives.
They were very primitive but also very powerful and deadly.
The idea for making improvised grenades of these type was born in Vukovar by it's croatian defenders and soon after that, the production started by croatian soldiers in Dubrovnik,Vinkovci and Karlovac.

There were three different types of these improvised grenades, all of them have in common that empty beverage cans were used as a body of the grenade and pyrotechnical slow burning fuze with detonator No.8 as its fuze. Variations among these types are just in technique of making them and in explosive filler and fragmentation.

On the right: Coca cola would do the same job.





First type:
After filling the emty can in 1/3 of its volume with that improvised fragmentation, melted TNT from unexploded Yugoslavian people's army artillery shells or powdered Vitezit was put in other 2/3 of the can. Then the cavity for detonator was made in explosive filling and pyrotechnical slow-burning fuze with detonator No.8 was put through the hole on the upper part of the can. Finally epoxy was charged around slow-burning fuze to prevent detonator to come off the can and to protect the content against moist. Various length of slow-burning fuze were used, fuze delay varied from 4 to 10 seconds.

Second type:
The empty can was cut open on the top side. An original plastic tube of Vitezit V20 explosive was cut to get about 100 grams explosive charge. That Vitezit V20 charge was put in the centre of the can and various metal waste (nails,pieces of rusty steel wire,screws and bolts were put around the explosive charge to fill the can up to about 1 cm from its top. Slow-burning pyrotechnical fuze with detonator No.8 was put in explosive charge. After that melted wax was poured above explosive charge and fragmentation to protect the explosive and improvised fragmentation against moist and to keep the fuze from falling out after throwing the grenade. Also various lengths of pyrotechnical slow-burning fuze were used, fuze delay varied from 4 to 10 seconds.

Third type:
The empty can was cut on cross on its top side, and the four parts of its upper cap were bend open to make the inside of the can free for filling with Vitezit and fragmentation material. A Vitezit charge was cut in the same length as a length of the empty can and was set in the centre of empty can. Steel nails about 12 cm in length were put around the Vitezit charge as improvised fragmentation. Slow-burning pyrotechnical fuze with detonator No.8 was put in Vitezit charge and four parts of upper cap of the can were bend back in normal position to close the can. Then the top of the can was completly taped with duct-tape to secure the fuze and charge after throwing the grenade. This type was mostly made by croatian soldiers in city of Nova Gradiška at the beginning of 1991. Slow-burning pyrotechnical fuze was about 10 cm long on this type so fuze delay was about 10 seconds.



Dimensions of all three types :

Length(body) : 117 mm
Diameter: 65 mm
Explosive filler : 200 grams of TNT or Vitezit(first type) or 100-150 grams of Vitezit V20(second and third type)
Type of the fuze : pyrotechnical slow-burning fuze with detonator No.8
Fuze delay : various(4-10 seconds)
