In any Chaos turn where the Chaos player hasn't declared a charge with them, Screamers can attack an enemy unit which is not inside a wood or a building by moving over it during the Remaining Moves part of their Movement phase. This inflicts an automatic Strength 3 hit per Screamer and the enemy cannot fight back — these hits count as missile hits and may force a Panic test. A Screamers unit may only use this special attack against one enemy unit per turn, even if they fly over more than one unit in that Movement phase.
