Some tactics that were used in WWII would be things such as fighter-bomber aircraft bring employed for tactical missions. These aircraft were heavily armed and capable of withstanding steep dives and rapid maneuvers. Their heavy armor protected them from some of the ground fire they encountered on low-level missions. Their missions included striking enemy armor and their defense positions, destroy any supplies or communication centers located in close proximity to the battlefield and also to hassle troops positioned behind the lines. Another form of tactics was an airborne assault. This is when paratroopers and glider troops became highly utilized during WWII. By dropping these troops behind enemy lines, these forces could impair the enemy’s key positions and installations. Airborne assault was widely utilized during the Normandy invasion.
