Up to date doctrines and a decent admiral make an enormous difference. In one of my first games as Brazil, all of the heavy ships in the Italian Navy had been sunk by the Brits. I attempted a landing on Sicily and the 27 light cruisers and destroyer flotillas they had remaining sortied to stop the landings. My small navy was built around a SAG of five CAs and a destroyer screen. But four of the CAs were repairing in port. That lone CA sunk the entire Italian Navy in one three day battle while my landings were completed. Scary.
