Fanatics must be released when an enemy unit comes to within 8" of the concealing unit's Line of Sight. The moving unit stops immediately (fliers land). Once the Fanatic's movement has been resolved, the unit can continue moving if the controlling player wishes, although chargers must complete their charge unless panicked. When a Fanatic is released, you may choose the direction in which it travels, and the point on the concealing unit from which it starts. Fanatics move 2D6" using the rules for Random Movement, measured from the base of its unit. After release, Fanatics are treated as individual units. In your subsequent turns they must move in the Compulsory Moves subphase using Random
Movement, but they always move in a random direction.
