Hello, quick question.
Steal an Advantage says: This Strategy's ability is Battle/Engage if you control a Scout at this battlefield. Battle: A target enemy card may not use one of its abilities (you choose).
Entrenched Position says: Interrupt: Negate a Battle action's effects taken by the Attacker if it is taken before the Defender's first normal opportunity to act or pass.
If Steal an Advantage is used with a scout at the battle field as a Battle/Engage does it still count as a battle ability giving me the opportunity to Entrenched it?

No.
When taking an action that has multiple action types (such as Battle/Engage or Battle/Open), for purposes of other cards looking for the action type played, it depends on how the original action was used. If it's played as a Battle it's affected by cards that affect Battle actions; if it's played as an Engage it's affected by cards that affect Engage actions.
