Reconnaissance Squad

"The Move Through Cover Special Rule allows the penalties of terrain to be ignored."
A Unit that includes at least one Model with the Move Through Cover Special Rule ignores the effects of Difficult Terrain and Dangerous Terrain. If called upon to take a Dangerous Terrain Test then such a Unit is assumed to automatically pass without any Dice being rolled.

"A Unit that contains Models with this Special Rule scores fewer Victory Points for Controlling Objective Markers."
A Unit that includes any Models with the Support Unit (X) Special Rule may only ever score a maximum number of Victory Points equal to the value of X for Controlling an Objective, regardless of the Value of that Objective, or any other Special Rules Models in that Unit might have (such as the Line (X) Special Rule).

"Models with the Infiltrate (X) Special Rule can deploy outside of their Deployment Zone." 
At the start of a Mission, when deploying Units, the Controlling Player of a Unit that is composed entirely of Models with the Infiltrate (X) Special Rule may choose to deploy that Unit outside of that Player’s Deployment Zone. That Unit may be deployed anywhere that is either in the Controlling Player’s Deployment Zone or outside of the Opposing Player’s Deployment Zone and is at least a number of inches equal to the highest value of X attached to any variant of the Infiltrate (X) Special Rule in that Unit away from any Enemy Model.

Units deployed using the Infiltrate (X) Special Rule are deployed at the same time as other Units under a Player’s control, unless the specific Rules of a given Mission state otherwise. The Infiltrate (X) Special Rule only has an effect when deploying Units before the start of the First Turn of a Battle, and Units deploying on the Battlefield after the First Turn has begun gain no benefit from this Special Rule. A Unit that is deployed outside of the Controlling Player’s Deployment Zone by means of this Special Rule may not have a Charge declared for in the Firs Battle Turn.
