You should add a feature to where if more than three tanks are near a player with 100% and the player uses the Overdrive, the tanks near will get a boost and all tanks that got the boost will have a godmode that only lasts 7 seconds (this would only be for the tanks that got the boost, including the tank that started the boost, and not just one lone tank that boosts itself.) The godmode would make a shield around the tanks even if they move away from each other, and in the five seconds, the tanks will be protected from enemy shots but CAN NOT fire back until the 7 seconds is over.
