And They Shall Know No Fear A unit that contains at least one model with this special rule automatically passes Fear and Regroup tests. When it Regroups, the unit does not make the 3" Regroup move, but can instead move, shoot (or Run) and declare charges normally in that turn. Furthermore, if a unit containing one or more models with this special rule is caught by a Sweeping Advance, they are not destroyed, but remain locked in combat instead.
Counter-attack If a unit contains at least one model with this special rule, and that unit is charged, every model with the Counter-attack special rule in the unit gets +1 Attack until the end of the phase.
If, when charged, the unit was already locked in combat, the Counter-attack special rule has no effect.
Acute Senses If a unit contains at least one model with this special rule, and that unit arrives on a random table edge (due to Outflank, or other special rules), then you can re-roll to see which table edge they arrive from.
