Germany undertook to reduce its armed forces to no more than 370,000 personnel, no more than 345,000 of whom were to be in the Army and the Air Force. These limits would commence at the time that the Treaty on Conventional Armed Forces in Europe would enter into force, and the treaty also took note that it was expected that the other participants in the negotiations would "render their contribution to enhancing security and stability in Europe, including measures to limit personnel strengths."[4] Germany also reaffirmed its renunciation of the manufacture, possession of, and control over nuclear, biological, and chemical weapons, and in particular, that the Nuclear Non-Proliferation Treaty would continue to apply in full to the unified Germany (the Federal Republic of Germany). No foreign armed forces, nuclear weapons, or the carriers for nuclear weapons would be stationed or deployed in six states (the area of Berlin and the former East Germany), making them a permanent Nuclear-Weapon-Free Zone. The German Army could deploy conventional weapons systems with nonconventional capabilities, provided that they were equipped and designed for a purely conventional role. Germany also agreed to use military force only in accordance with the United Nations Charter.[1]
