Finnish four-man Molotov cocktail crews destroyed nearly 2000 tanks. The Soviet tanks had an extra 50 gallon gas tank on the back end of the tank near the engine air vents. The tanks were noted for their poor maintenance and excess grease and oil in the engine compartment. The tank would be allowed to penetrate the tactical wire. One man with a log would attempt to jam the tracks while the two Molotov Cocktail men would throw their weapons on the back end of the tank. The gasoline and alcohol would drip into the engine compartment where heat would ignite the mixture and the engine compartment would burst into flames. This would in turn ignite the 50 gallon gas tank on the back of the tank and create tremendous heat inside the tank. The tank crew would attempt to escape and the man with a sub machine gun would kill the crew. Casualties among the Molotov cocktail crews were about 75 per cent.
