i really think you should be able to take your own cruiser (5'' guns) by yourself, if you beach to cant move and you slowlylose hp (if the enemy air doesnt get you) also there should be personal submarines too... go down, pop upshoot that sing barrel 5'' at unsuspecting fleet, torps too. (10 min re-arm) of coars youd put sonar on cruisers, with depth charges.
also, when a ammo ship blows, it should shoot .5 cals in all directions plus 500' blast, only hurting nonfleet vehicles...
well maybe not, but ju88's should be downed if they stick around, because of the blast.
