If a unit is armed with missile weapons and can draw a line of sight to the charging unit, it may declare that it will attempt to Stand & Shoot. Measure the distance between the two units. If the distance is less than the Movement characteristic of the charging unit, the charged unit is unable to raise its weapons in time and must either Hold or Flee instead.
Otherwise, even if the distance between the two units is greater than the maximum range of the charged unit's weapons, the charged unit will shoot at the charging unit. Once this shooting has been resolved, the charged unit will Hold and await the charging unit. Charging units are not required to make Panic tests.
Fleeing units and units already engaged in combat when charged cannot Stand & Shoot.
