Cleave

This ability always takes the form [CLEAVE X]. Each time you gather attack dice for a [CLEAVE] weapon, if you only selected one target for all of that weapon’s attacks, add X additional attack dice for every five models that were in the target unit in the Select Targets step (rounding down).  ***Example: If a *[CLEAVE 1]* weapon with an A characteristic of 3 targets one unit containing 16 models, you would gather three additional attack dice for that weapon (for a total of six for that weapon).*
