How did the Treaty of Versailles limit Germany’s military forces?

To ensure Germany would not again pose a military threat, the Treaty of Versailles imposed strict limitations on its armed forces:

• Army: The German army was restricted to a maximum of 100,000 men, and the general staff—viewed by the Allies as the engine of German aggression—was ordered to be dissolved.123
• Armaments: Germany was strictly prohibited from producing tanks, poison gas, military aircraft, and armored cars. The production of weapons and munitions was limited to a small number of specified factories.123
• Navy: The navy was significantly dismantled, limited to 15,000 men, six battleships, and 30 smaller vessels. The construction of submarines was absolutely forbidden.12
• Demilitarization: The Rhineland was permanently demilitarized. German military forces were prohibited from entering the area west of the Rhine River and a 31-mile (50-km) strip to its east.1423

Compliance with these measures was monitored by the Inter-Allied Commissions of Control and enforced through the occupation of the Rhineland.12
