14.1.1 - Objective Marker Control

After set-up has been complete but before the first turn battle round begins, each player gains control of all objective markers within 6" of any friendly models and more than 6" away from any enemy models. In addition, at the end of each turn (after the Combat Phase), you must check to see if you have gained control of any objectives. To do so, count the number of friendly models that are Contesting the objective (see 14.1.2).

You gain control of the objective if there are more friendly models than enemy models contesting it.
