The infantry has always had the worst of any war. Even so, by the 1930s planners decided to make the infantry a more effective weapon and the British Government had the Carden-Lloyd Carrier developed. The German Blitzkrieg took this development a quantum leap further with the Hanomag armoured personnel carrier (APC), employed by Rommel's Afrika Korps. The British response was the half-ton Universal carrier. The Soviet Union created the amphibious BMP series, since the Red Army knew that if ever invaded West Europe it would have a lot of rivers to cross. The United States produced the M1-13 in the early 1960s, the longest serving and most widely exported personnel carrier of all time, which saw active service as late as the Gulf War in 1991. It was the first vehicle in the world to use aluminium armour to reduce weight and is fully amphibious. To complement it, the M2 Bradley emerged in 1981 after 20 years of development. Equipped with a chain-gun capable of firing 600 rounds a minute and 2 TOW missile launchers, the Bradleys, together with the British Warriors, swept through Iraqi minefields with such speed that Saddam's troops were unable to deploy. Within a week the armoured infantry mission was accomplished.
