Stupidity

Unless in close combat, a unit with a Stupid model must pass a Leadership test at the start of its Movement phase or move directly forward using Random Movement (D6) in the Compulsory Movement sub-phase and take no further action that turn (no charges or shooting), though outside effects can still force it to move or act. Until it passes the test again, it has Immunity (Psychology) and Random Movement (D6), may only move directly forward, and can't reform or choose any charge reaction except Hold. Wizards in the unit cannot cast, channel or dispel.
