D Day

U.S was officially in the war with entering a long battle (D-day). The objective of the U.S was to secure Normandy in France and the nazis had defenses set up on the beaches making it very difficult for the U.S to attack from the beaches. The U.S figured this, and sent fleets of paratroopers behind nazi lines to flank the nazi defenses and then destroy them to allies can then advance. This was the first battle the U.S has ever used paratroopers and it was pretty successful.
