After World War I, while France and other Allies were building military defenses modeled on trench warfare, German commanders were shaping a nimble fighting force.

General Atomics, the progenitor of General Atomics Aeronautical Systems, started life in 1955 when a major military contractor, General Dynamics, feared that the military hardware market might dry up. It began exploring peacetime uses of atomic energy, but abandoned the effort when cold-war military spending took off.

In 1940, Germany toppled France in 20 days, and the panzerdivizion symbolized war's shift from drawn-out conflicts using massive fortifications to rapid-fire engagements built around manned, motorized armor.
