tanks shouldn't be good in cities without infantry support, or without infantry support in general. Tank swarming with infantry was a good way to get tanks killed.
I've seen things, you recruits wouldn't believe. Attack bots in flames because they didn't know how to put out a fire. I've seen HEAT metal beams, vanishing in the darkness of an indestructible tank optic. And all these moments will be lost, like your bot squadmates in a mortar rain. Time to die.
