An army with the Disruption Force Disposition facing one with Reconnaissance is dealt Smoke and Mirrors as its primary mission.
The opposing army is not playing the same mission: it is dealt Surveil the Foe. Reading only your own card is how a game gets lost from in front.
Disruption against Reconnaissance. The Decoy action (Shooting phase; a friendly unit within range of an undecoyed non-home objective; unlimited uses, one objective each; completes at end of turn if the unit controls that objective) decoys the objective and places one of your operation markers within range of it. Each decoyed objective pays at the end of your turn, with a stacking per-objective bonus for those in the opponent's territory. From the second battle round, non-home control pays at the end of your Command phase. End of battle pays a large bonus if four or more objectives are decoyed.
Primary scoring is capped at 15 victory points in a battle round and 45 across the game.
