Tier
A vehicle's rank from I to X, which sets its power level, its battle tier spread and everything about its economy.
Also known as tiers, vehicle tier.
Tiers run from I to X in the tech trees, with a Tier XI progression sitting above X for a few branches. Each step up brings more hit points, more damage and better armor, and a two-tier gap is large enough that the lower vehicle cannot fight the higher one directly.
Tier also decides costs. Repairs and ammunition scale steeply, so Tier X loses credits without a premium account, and it decides which battle tiers a vehicle is pulled into.
