Barbgaunt Brood

see Instinctive Behaviour

A unit that Lurks may not move in the Movement phase and may not launch an assault in the Assault phase. in the Shooting phase, the unit must fire at the nearest visible enemy. If there are no enemies in the unit's line of sight or within range of at least one of its ranged weapons, or if the unit has no ranged weaponry, it must instead run towards the nearest piece of area terrain, trying to move into it if possible. If the unit is already in a piece of area terrain it will not move and will stay where it is.

Models with claws and teeth count as having a normal close combat weapon.
