Blitzkrieg

Blitzkrieg was a way of fighting wars for Germany during WWII. It was a quick and powerful way to attack the enemy quickly before they had time to prepare. They would use fast tanks and airplanes to come into a country before the other country was ready, and then they used infantry and other ground troops to take over the land they wanted. This way they could take over land quickly and with minimum casualties (people getting killed or injured). It was a successful way of fighting for Germany during WWII.
