A couple of times I've run across abandoned tanks and my own tanks were unable to target and destroy them despite being right next to them. Is this meant to be this way? I'd prefer to be able to destroy them. Thanks
If I remember correctly, it is possible to destroy them. Place one of your units above (with the shift key) and the next round will be destroyed (abandoned vehicles or bunkers). Otherwise, at the end of the game, if you win (condition to check), they will be automatically deleted.
