Y U NO BOOST YOUR BO AND RADIOMAN?! Overvetting them is a good idea, too.
Anyhow, I knew I was doing the right thing all along! But... I think you forgot one thing. Crossing! Cross like there's no tomorrow, and your allies will gain valour and courage and will kill the enemy faster. ALWAYS cross the biggest and baddest BB when he's fighting, that'll boost his morale because your boosted elite and overvetted radioman will give his sailors an edge over the weak enemy.
