# Battle tier

The tier bracket a battle is fought at, which is what decides who a vehicle meets rather than its own tier alone.

Also known as MM spread, tier spread, matchmaking tier.

Every vehicle has a range of battle tiers it can be pulled into, normally its own [tier](/glossary/tier.md) and the two above. A Tier VIII therefore sees [battles](/glossary/battles.md) at VIII, IX and X, and the position it holds in the list changes what its job is.

Some vehicles have a deliberately narrower [spread](/glossary/dispersion.md). Most [premium vehicles](/glossary/premium-tank.md) and a few researchable ones see only one tier above their own, which is why they are described as having [preferential matchmaking](/glossary/preferential-matchmaking.md).

[Bottom tier](/glossary/bottom-tier.md) is not a penalty box. A vehicle two tiers down cannot [trade](/glossary/trading.md) shots with the [top of the list](/glossary/top-tier.md), so its value moves to [spotting](/glossary/spotting.md), [flanking](/glossary/flanking.md) and finishing, which is exactly the shift the [matchmaker](/glossary/matchmaking.md)'s template forces on two thirds of every team.
