On burning bridges , put the 4 commandos on albatross and protecting your mortars and rocket , putting your ranged at a chokepoint and then once you killed the enemy commandos , wait for your partner's tanks to attack !
I agree with firgreen and Windyful .. this game needs a boss cat who will kill cats and the shamans are required to kill it and the mouse are required to like listen to the shaman and the cat and shamans should have same weapons , there also should be more shamans if there is a cat . Like 10 mouse in the room = got 1 cat and 3 shamans , 20 mouse in room = got 2 cats and 6 shamans etc. !
