Each time you hit a target unit with a markerlight, put a counter by that unit. The counters remain until the end of the current Tau Shooting phase or until they are used. Counters may be expended by subsequently firing Tau (and Vespid units, so long as the Strain Leader is alive) firing at the 'marked' unit. Every counter expended grants the firing unit one of the following effects, which may be combined.

• To allow a vehicle to fire a single seeker missile at the marked unit. This shooting is resolved normally in all regards at an assumed Ballistic Skill of 5.

• To allow a unit which fires at the target to do so at +1 to its Ballistic Skill. This effect may be stacked, allowing a a Ballistic Skill up to a maximum of 5.

• To allow the firing unit to ignore the effects of the Night Fighting rule when shooting at the marked unit.

• To impose a -1 Leadership penalty on the marked unit for the purposes of any Pinning test imposed by the firing unit's shooting. Multiple counters may be expended to impose a cumulative modifier.

• To impose a -1 penalty on any Cover Saves the marked unit may have from the effects of the firing unit's shooting. Multiple counters may be expended to impose a cumulative modifier.

In any case, the use of a counter must always be declared before to hit rolls are made by the firing unit, and the counter is only removed after rolls to hit have been made, so if the firing unit is distracted by a closer target or cannot see the target unit because of the Night Fighting rule (or any other reason) the counter is not removed.

Markerlight shots do not benefit from the effects of other markerlights.
