Sniper -- Standard Rifle (Any (quality depends on group))

Notes

Agile: Agile units ignore movement penalties when crossing Difficult Terrain.
Elusive: Once per turn, when an elusive unit is fired upon, they may fall back 4” before shooting is resolved. Measure range and calculate terrain benefits from their new location. If Line of Sight is lost, the shooting unit is free to select another target.
Stealth: A unit with this ability always succeeds when it goes into hiding (see Hidden Movement). There is no die roll required.
