In the early years of WWII, the German "Luftwaffe" focused on tactical bombing, using large numbers of Ju 87 Stukas as "flying artillery" for land offensives. Artillery was slow and required time to set up a firing position, whereas aircraft were better able keep up with the fast advances of the German panzer columns. Close air support greatly assisted in the successes of the German Army in the Battle of France. It was also important in amphibious warfare, where aircraft carriers could provide support for soldiers landing on the beaches.
