Target squad goes into Stealth: (+1 grey stud on stsk). A unit in stealth cannot be targeted. When you would move a stealthed unit, choose one, either add a stealth stud (max2), Or move it up to its mvt stat for each stealth stud on the statstick, then you may use an action, stealth ends. Performing an action or being targeted by detection removes stealth. Attacking out of stealth from behind requires 2 less to crit.
