Outflank
(Rule)Description: Instead of being deployed on the battlefield as normal, if all models in a Detachment have the Outflank special rule, the Detachment may be placed in Reserve. While in Reserve, Detachments with the Outflank special rule can only be issued the Advance Order or March Order.
When a Detachment with the Outflank special rule that is in Reserve is activated in any Movement phase other than the first, the controlling player may choose to leave it in Reserve or Flank the enemy. When a Detachment Flanks the enemy, the controlling player places the models in that Detachment in base contact with any battlefield edge, although no model can be deployed within 8" of the enemy's battlefield edge. Once deployed in this way, the Detachment may complete its activation as normal (i.e., it may move during the Movement phase and/or fire during the Combat phase, etc.).
