nuke main_battle_tank
nuke light_tank
nuke heavy_tank
Seems like such subtag of a tank class is not going to be necessary because most viewers in general cannot discern which one is an MBT, light tank, heavy tank or such. Armour thickness and its gun caliber are not even distinct. Does not feel like deprecation will be better idea.
I consider turretless tank deserve staying because they are visibly distinguishable.

I don't see what a mass update will do after the tag is nuked.
Originally I proposed a mass update in case posts containing such tags are missing the actual tank tag.
