A lower BridgeStrength makes bridges easier to damage. The same value is also the damage of the charge an infantryman sets to demolish a bridge.

A blast can damage a bridge span in its own cell only when all of these hold:

  • bridge destruction is on: DestroyableBridges in a campaign, or the BridgeDestruction option in any other game;
  • the warhead sets Wall=yes;
  • at an elevated bridge, the blast goes off near deck height, so a blast on the ground beneath the span cannot damage it.

The blast then rolls a whole number from 1 to BridgeStrength and damages the span when the roll is below the blast’s raw damage, before armor. A blast of 200 damage against BridgeStrength=1000 succeeds 199 times in 1000. At BridgeStrength=1, any blast of 2 or more damage always succeeds.

A blast with IonCannonWarhead skips the roll. At an elevated road or rail bridge, it also gets up to four attempts at the span and stops at the first that succeeds. Every other warhead gets one attempt. At a low bridge, the ion cannon skips the roll but otherwise damages the span like any other warhead.

When an infantryman demolishes a bridge from its deck, three blasts go off at its feet, each with BridgeStrength damage and C4Warhead. The first is credited to the infantryman and the other two to nobody. Raising the value to make bridges harder to shell therefore also makes this charge deadlier to everything standing nearby.
