Overmatch

Caliber Overmatch Rule (3× Rule)

In one sentence:

When shell caliber is ≥3× armor thickness, ricochets become impossible and angle modifiers are reduced.

What it means

Overmatch is a 'thick gun beats thin armor' rule. If your shell's caliber is at least 3 times the thickness of the armor plate it hits, two things happen: (1) ricochets are impossible regardless of impact angle, and (2) the angle's effective armor multiplier is reduced. This single mechanic explains why huge-caliber derp guns can punch through angled light tanks and SPG roofs that should statistically deflect them.

How it's calculated

Overmatch trigger: shell_caliber ≥ 3 × armor_thickness. Below trigger: standard slope rules apply. Above trigger: ricochet disabled, angle penalty reduced.

Typical values

Common overmatch breakpoints: 122mm shell overmatches up to 40mm armor; 152mm/155mm shells overmatch up to 50mm armor; 100mm/105mm shells overmatch up to 33mm armor.

Example

A 152mm shell hits the 30mm roof of a Bat.-Châtillon. 152 ≥ 30×3 (90) — overmatch triggered. The shell penetrates regardless of the 80°+ angle of the roof. A 100mm shell against the same target would ricochet.

Why it matters

Overmatch shapes top-tier brawls. Heavies with 30mm roofs cannot 'angle' against 152mm derp guns — they must avoid the line of fire entirely. Conversely, big-caliber guns can ignore the slope of light-tank top plates and farm them through normally-impenetrable angles.

Common pitfall

⚠ Assuming an enemy can never penetrate your angled hull. If they have ≥3× your armor caliber, your angle doesn't help — and you eat full damage believing you were safe.
