Big Red Rulebook, page 146
Scoring Units
Any unit taken as a troops choice (not including attached dedicated transports) and other units whose Army List entries specifically note it, can be a scoring unit, unless:
It is a swooping flying monstrous creature, a zooming flyer, or is a unit currently embarked on as zooming flyer.
It has a special rule specifying that it never counts as a denial unit.
It is currently falling back (if the unit regroups, it immediately reverts to being a scoring unit again).
It is a building or fortification.
Seems pretty clear - taking it as a troop choice? Scoring.
All good?
