Answer 2

The first thing I start thinking about is the combat strategies used during WWII. Also have in mind what point the war was in, 1942 (of the whole 39-45). There are other things too, such as warfare on certain sides of the globe; in this case, it's against the Japanese:

"The principal weapon of the submarine, and of some surface vessels, was the torpedo. One of the most successful torpedoes was the Japanese "Long Lance," which was used to sink four cruisers at the Battle of Savo Island (1942). Late in the war, the Germans introduced homing torpedoes guided by the sound of the target ship's propellers. Aircraft Carriers. The most significant development in naval warfare in World War II was the use of aircraft carriers as capital ships—that is, as the main warships of a fleet. Before the war, aircraft carriers were generally viewed as support ships, intended to provide air protection and air reconnaissance for battleships. The Japanese attack on Pearl Harbor showed the carrier's potential as an offensive weapon. In May, 1942, the Battle of the Coral Sea, fought entirely by carrier-based aircraft, took place. It was the first naval confrontation in history where the opposing fleets never came within sight of each other and were never close enough to exchange gunfire. From that point on, the carrier was the dominant warship in the war in the Pacific."

More importantly, "the Aleutian Islands Campaign, the only major ground operation to occur in the hemisphere during the war."
