"How do you beat 2-4?
Have a fleet of level 30 ships fully modernized consist of at least 2 BB and any ship which could endure the long fighting you'll about to face (4BB+2CV is good). Along the way, use line abreast formation (the 5th) and line ahead when engaging the boss."

I have read most of the combat mechanics and I think line ahead is supposed to be good against everything except subs? Can someone explain to me the reasoning behind using line abreast?
