Air campaigns today are built around cooperation between many different aircraft, each performing a specific task. Stealth fighters lead the way into contested airspace, electronic warfare aircraft disrupt enemy radar, and bombers or strike fighters deliver precision weapons. Supporting aircraft provide intelligence, command and control, and the fuel needed to keep the entire operation moving.
Tanks became a central part of how armies fought, and certain designs quickly gained reputations among soldiers who faced them in combat. Some were feared for their firepower, others for their armor or battlefield dominance.
WWII began with most naval powers still believing the battleship ruled the seas. Fleets were built around heavily armored ships with massive guns meant to destroy enemy navies in decisive surface battles. By the war's end, that thinking had changed dramatically. Aircraft carriers could strike targets hundreds of miles away, while submarines choked off supply lines across entire oceans.
Germany started the First World War (1914-18) with the belief its armed forces could win a quick and decisive victory over France and then Russia. The reality turned out to be much more complicated as more countries became involved in a global war that lasted five years. An alternative title to this article, of course, could be How the Allies Won the War.
The German Spring Offensive, also called the Ludendorff Offensive after its commander, was the last major German advance of the First World War (1914-18). From March to July 1918, Ludendorff launched five major attacks on the Western Front to break the deadlock of trench warfare. The Allied resistance, use of tanks, and massive reserves, along with German logistical failures, meant that the offensives, despite each starting well, eventually petered out.
