no, abilities only apply to the unit that has them

you also dont get stealth now. so defeats purpose.

Spec forces like Navy seal unit.. get in undetected kill and get out. SEALS dont roll with normal infantry; but a QRF (quick response force made up of air/inf support) is on call to come to rescue (although SEALS probably dont use that term )and extract SEALS if things go south. But mostly if deep behind enemy lines or across wrong line on map; spec forces are on their own.

Like any combination if I combine ASF with bombers my range goes down to ASF range. No free lunch in game.

Only units that add to others units are officers; they dont give all super powers but will boost attack/defend of every unit in stack; thats why I like 4 frigs/1 officer with the boost its like having 6 ships in a 5 ship stack. Think Air officers give whole stack speed boost too??

yeah

NOOB TIP: KEEP ALL STEALTH IN 1 STACK! (if mix stealth and nonstealth ALL units appear so wastes surprise)
