Lifeboats?
I HOSE them!
Twin 20mm is my favorite but running over them is a lot o fun too.
IJN gets no mercy from me! I just picture Nurse Bullwinkle and her mates getting marched into the surf and machine gunned. Merchant marine I let live.
Just be careful in TMO-the standard lifeboat loadout is ammo! The boats are worth a ton each, the rafts get you nothing but a warm feeling inside knowing a few less IJN personnel are going to be beating captured airmen or raping Dutch and Australian nurses to death.
PS it's a game...
