The fighting in WWII differed from WWI in several ways. In WWII, the use of technology and weaponry was more advanced, with tanks, planes, and submarines playing a significant role in battles. Additionally, WWII saw more widespread and brutal tactics, such as the bombing of civilian populations and the use of concentration camps, which were not present in WWI. Finally, the scale of combat in WWII was much larger, with battles taking place on multiple continents and involving a greater number of countries.
