Yeah that’s cool, but it’s so impractical. It requires other tanks for support, and to do any actual damage to enemy tanks. It would almost certainly be more effective to just shoot an enemy tank with an armor piercing shell than to try to disable its optics. The laser tank can be almost immediately rendered useless by a single foot soldier with a rifle who shoots out the lenses. If it were capable of disabling multiple enemy tank optics before being disabled itself, and those lack of optics turned the tide of the battle, then it would be a valuable addition to an army, but I have a hard time believing it would ever actually play out that way. It would get insta-targeted by everyone on the field, and promptly removed from the battle.
