Solar Auxilia Command Tank A model with this special rule is selected as a separate unit, but during deployment must be assigned to another unit and may not be deployed as a separate unit. If multiple appropriate units are available, the controlling player chooses which unit a model with this special rule is assigned to. Once assigned to a unit, a model with this special rule counts as a part of that unit and may not leave the unit during play for any reason. A Leman Russ Command Tank must be assigned to a Leman Russ Strike Squadron or a Leman Russ Assault Squadron.
Tercio Models with this special rule may only be selected as part of a Tercio (see the rules for Tercios on page 68). When a Reaction is declared for a unit with this rule that allows it to make a Shooting Attack or Move, then all units from the same Tercio that are ‘In Formation’ with the Reacting unit may also Move or make a Shooting Attack as described in the Reaction being made (all units that Move or Shoot are counted as having made a Reaction, and thus cannot make further Reactions in the same Phase, and must target the same unit with any Shooting Attacks made). A unit is ‘In Formation’ when that unit is in unit coherency and has at least one model within 3" of a model from a different unit in the same Tercio that is also in unit coherency.
