Francis E. Warren Air Force Base (AFB) (IATA: FEW, ICAO: KFEW, FAA LID: FEW) is a United States Air Force base located approximately 3 miles (4.8 km) west of Cheyenne, Wyoming. It is one of three strategic missile bases in the United States. It is named in honor of Francis E. Warren.

Warren AFB is the home of the 90th Missile Wing (90 MW), assigned to the Twentieth Air Force, Air Force Global Strike Command. The 90 MW operates the LGM-30G Minuteman III ICBM, with launch facilities in Southeast Wyoming, Western Nebraska, and Northern Colorado. It is also the home of Twentieth Air Force, which commands all United States Air Force ICBMs.

Warren AFB is the oldest continuously active military installation within the Air Force, being established by the United States Army as Fort David Allen Russell in 1867. The facility came under United States Air Force control on 1 June 1947.

The 90th Missile Wing is commanded by Colonel Christopher Coffelt. Twentieth Air Force is commanded by Major General C. Donald Alston.

An airbase (sometimes referred to as a military airfield, military airport, air force station or air force base) is an aerodrome used by a military force for the operation of military aircraft.

An airbase typically has some facilities similar to a civilian airport - for example air traffic control and firefighting. Some military aerodromes have passenger facilities; for example RAF Brize Norton in England has a terminal used by passengers for the Royal Air Force's flights by TriStar to the Falkland Islands.

Many airbases are located remotely from populated areas.^{[citation needed]}

Some airbases have hardened aircraft shelters, or even underground hangars, to protect aircraft from enemy attack. Combat aircraft require storage of aircraft ordnance. An airbase may be defended by anti-aircraft weapons and force protection troops.

Road airbases are highways constructed to double as auxiliary airbases in the event of war. Nations known to utilise this strategy are Sweden [1], Finland, Germany, Singapore, Switzerland, Turkey and Poland. In the case of Finnish road airbases, the space needed for landing aircraft is reduced by means of an arrestor wire, similar to that used on some aircraft carriers.[2]

In baseball, a force is a situation when a baserunner is compelled (or forced) to vacate his time-of-pitch base—and thus try to advance to the next base—because the batter became a runner. A runner at first base is always forced to attempt to advance to second base when the batter becomes a runner. Runners at second or third base are forced only when all bases preceding their time-of-pitch base are occupied by other baserunners and the batter becomes a runner.

A forced runner's force base is the next base beyond his time-of-pitch base. Any attempt by fielders to put a forced runner out is called a force play. A forced runner is out (called a force out) when a fielder with the ball touches the runner's force base before the runner reaches that base. A forced runner also may be tagged out in the usual fashion as well; such a tag is still considered a force play if the tag is made before the runner reaches his force base. Any play on the batter-runner before he reaches first base is the same as a force play, though the rules do not include this in the definition of a force play.

Frederick Edwin Smith, 1st Earl of Birkenhead GCSI, PC, KC (12 July 1872 – 30 September 1930), best known to history as F. E. Smith (and also Galloper Smith), was a British Conservative statesman and lawyer of the early 20th century. He was a skilled orator, noted for his staunch opposition to Irish nationalism, his wit, pugnacious views, and hard living and drinking. He is perhaps best remembered today as Winston Churchill's greatest personal and political friend until Birkenhead's death at age 58 from pneumonia caused by cirrhosis of the liver.

Smith was born in Birkenhead in Cheshire and was educated at Birkenhead School. After two years at the University College of Liverpool, he went up to Wadham College, Oxford, in 1896, where he was a contemporary of the politician John Simon and the athlete C.B. Fry. He became President of the Oxford Union, where a bust of him now stands. He obtained only a Second in Mods before switching to Law, in which he obtained a First. However, to his disappointment, he only obtained a Second in his Bachelor of Civil Law degree. After winning a Fellowship of Merton College he taught law at Oxford until 1899, when he was called to the Bar at Gray's Inn, where the Birkenhead Award bears his name. The F.E. Smith Memorial Mooting Prizes commemorate him at Merton.
