Although the British Army was a major participant in Korea in the early 1950s and Suez in 1956, during this period Britain's role in world events was reduced and the army was downsized. The British Army of the Rhine, consisting of I (BR) Corps, remained in Germany as a bulwark against Soviet invasion. The Cold War continued, with significant technological advances in warfare, and the army saw the introduction of new weapons systems. Despite the decline of the British Empire, the army was engaged in Aden, Indonesia, Cyprus, Kenya and Malaya. In 1982, the British Army and the Royal Marines helped liberate the Falkland Islands during the conflict with Argentina after that country's invasion of the British territory.
