What were the major military strategies and tactics used during World War II?

During World War II, the major military strategies and tactics used by various nations included:

1. Blitzkrieg: This was a German tactic that involved rapid and coordinated attacks using tanks, aircraft, and infantry to quickly overwhelm the enemy and disrupt their defenses.

2. Island hopping: This strategy was employed by the Allies in the Pacific theater, where they selectively targeted and captured key islands to establish airbases and gradually move closer to Japan.

3. Strategic bombing: Both the Allies and Axis powers extensively used strategic bombing to target enemy infrastructure, industrial centers, and civilian populations. This tactic aimed to weaken the enemy's ability to wage war and break their morale.

4. Amphibious assaults: The Allies utilized amphibious assaults, such as the D-Day invasion of Normandy, to establish a foothold on enemy-held territories and launch offensives from there.

5. Guerilla warfare: Resistance movements and partisan groups employed guerilla tactics, including sabotage, ambushes, and hit-and-run attacks, to disrupt enemy supply lines and communication networks.

6. Naval warfare: Naval strategies involved the use of aircraft carriers, submarines, and battleships to control sea routes, protect convoys, and engage in naval battles.

7. Defensive strategies: Nations also employed defensive strategies, such as building fortified lines and defensive positions, to hold off enemy advances and protect key territories.

These strategies and tactics played a crucial role in shaping the outcome of World War II and had a significant impact on the course of the conflict.
