An army with the Disruption Force Disposition facing one with Priority Assets is dealt Locate and Deny as its primary mission.
The opposing army is not playing the same mission: it is dealt Extract Relic. Reading only your own card is how a game gets lost from in front.
Disruption against Priority-Assets. At the start of the battle, place one of your operation markers in each of five terrain areas outside your deployment zone (or in every such terrain area if fewer than five). The opponent's Sensor Sweep removes them; your own Sensor Sweep (Shooting phase, a friendly unit within range of a central objective, once per turn, completes at end of turn if the unit controls that objective, cannot start while only one marker remains) also removes one marker. Kills on enemy units that started the turn on objectives pay at end of turn, as does being down to exactly one of your markers with a friendly unit alone in its terrain area - the same condition pays again at the end of the battle. From the second battle round, non-home control pays at the end of your Command phase.
Primary scoring is capped at 15 victory points in a battle round and 45 across the game.
