Is this pretty much true overall the purpose of these vehicles are to combat other types of vehicles
Heavies > TDs
Heavies < Mediums
Mediums < TDS
Mediums can flank and take out Tank destroyers
Heavies can take out mediums in frontal engagements preventing them from advancing through a flank.
Tank Destoryers prevent Heavies from advancing on a flank
If you wanted me to include Lights
Lights < Tds
Lights > Mediums
Lights = Heavies
Lights can flank TDS
Lights can't take on Mediums 1 on 1 most of the time
Lights can take over some Heavies, but some mobile Heavies can eat up light tanks as well.
I use this to play a wot Rock, Paper, Scissors game with my younger siblings.
Light, Heavy, Medium, Tank Destroyer - FIRE
