M8- that's like calling brummbar nondoc mobile arty. It's really not.
Churchills- piece of shit. Do I really need to explain why? It's not comparable to a kt or tiger in any world. It can't even fight any other tanks.
Comet- so that means panther is a heavy tank too? Because they are comparable, but comet can kill inf and panther has better armor/at abilities.
The m8 is literally a howitzer on wheels. it's functionally a mortar half track in what it does. It is lightly armored, has low health and does indirect fire.
The brummbar is a bunker buster/howitzer on wheels It is heavily armored, has a fixed turret and engages targets directly other than the bunker busting barrage. Their only similarity is their tier 4 unlock.
The churchill is a piece of shit against tanks because the brits have access to an excellent tank destroyer in the firefly which can stun enemy tanks. It would be better if the churchill could soak up AT damage better and actually act like the infantry tank it was.
The comet and panther have heavy armor and largely act as heavy tanks in the sense that they can 1v1 dominate a single tank from their opposing factions.
And yes, in my opinion the british do need a snare of some kind to deal with okw light vehicles that is not the AEC.
