True , but another , simpler way is the tried and true Molotov . In an urban area with multi story buildings , its not hard . Many German tanks were destroyed with those . You see , the partizans would hit the vehicle with 4-5 unlit bottles of gas first , this lets the liquid seep into vents , engine compartments , etc. ………….then they threw the lit one and set the whole mess on fire , and with any luck , were out of there before the infantry got to heavy .
