If the reinforcements are integrated into the ally's fleet, how does this affect scouting and stealth bonuses? If I supply a scout to an ally, can they gain rerolls or stealth bonuses or vice versa? And do I get the +1 bonus to beat stealth if one of my ally's ships has successfully attacked the target this turn?
Can I fire into a dogfight between my ally and the enemy?
