Starch and fiber are also considered complex carbohydrates but fiber can not be digested or used for energy. Starch is probably the most important energy source in an athleteâs diet because it is broken down and stored as glycogen. Foods high in starch include whole grain breads, cereals, pasta, and grains.
Conventionally, ICBM is a term used only for land-based systems, in order to differentiate them from submarine-launched ballistic missiles (SLBMs), which can also have an intercontinental range. As of this writing, only three countries have operational ICBM systems: the United States, Russia, and China.
ICBM, in full intercontinental ballistic missile, Land-based, nuclear-armed ballistic missile with a range of more than 3,500 miles (5,600 km). Only the United States, Russia, and China field land-based missiles of this range. The first ICBMs were deployed by the Soviet Union in 1958; the United States followed the next year and China some 20 years later. The principal U.S. ICBM is the silo-launched Minuteman missile. Submarine-launched ballistic missiles (SLBMs) with ranges comparable to ICBMs include the Trident missile, deployed by the United States and Britain, and several systems deployed by Russia, China, and France.
