-Find the man with C4s and give his detonator to someone else, then keep everyone back except for the man who has the C4. Immediately run to the tank and plant the C4. When you are finished, get another troop to call him back. When he runs back, the tank should be focused on him. Change to the man with the detonator and use it. If this works, everyone should make it out alive. However, if he does not make it, you can clear the area then heal him.
-Tick the tanks by using any of your men except the demolitions man and create a diversion on the side of the tank opposite to your team. Get the man next to the tank so that he will not be harmed, then switch to the demolitions man. While the tank is looking at the other man, sneak up to it, plant a C4 explosive, and get away.,
