not sure for tank but someone spawned a drone white round without anything outside sounding as jetpack and shooting explosive i tryed to destruct it qwith everything anti air and anti tank i found and he get no damage despit i have prohibited the invincibility in the setings aNd not showed a lockshield icon
i experimented than actuator canot be unsnaped form other bricks so i guess any vehicule made on an actuator skeleton is invincible and people often clip dozen of c4 tank in a missile or autoguided and genrally also clip dozen of canon in the same brick

mention that i found the sole workshop tank that the tracks dont broke :

saddly no weapon and no climbing capacity also a ridicule speed but i like the real tracks
i reached to remove the tracks in a negative slope so the actual speed is limited they dont broked but all the wheel suport so its like i thinked indestructible track that ttransfert all the force to other parts
as result a tank with real track have to be made exclusively of actuator for resist high speed and obivously it waste the war if all the tank are unbrokables
