Resistance groups could use captured tanks on occasion. I think it usually happened when they switched over to conventional operations from guerrilla warfare.
Here are three examples I can think of:
1) The Warsaw Uprising. The Polish Home Army (PHA) used several captured tanks and half tracks. Zoshka’s Storm Battalion used a tank to break into the Gesiowka concentration camp to liberate 400 Jewish prisoners.

2) The Battle for Paris. The ‘French Forces of the Interior’ used captured tanks against German strongpoints. These tanks were originally French tanks from 1940 and so some members of the resistance may have been familiar with them.

3) Yugoslavia. Tito’s Partisans were able to capture and use tanks on occasion. I vaguely remember reading somewhere that some of the captured Italian vehicles were driven by Italian defectors. Later in the war the Partisans also received allied tanks from the British and the Soviets.
