A court-martial (plural courts-martial, as "martial" is postpositive) is a military court. A court-martial is empowered to determine the guilt of members of the armed forces subject to military law, and, if the defendant is found guilty, to decide upon punishment.

Most militaries maintain a court-martial system to try cases in which a breach of military discipline may have occurred. Some countries, however, have no court-martial in time of peace; this is the case in France and Germany, for example, where ordinary, civilian courts are used instead.

In addition, courts-martial may be used to try prisoners of war for war crimes. The Geneva Convention requires that POWs who are on trial for war crimes be subject to the same procedures as would be the holding army's own soldiers.

Most navies have a standard court-martial which convenes whenever a ship is lost; this does not presume that the captain should be suspected of wrongdoing, but merely that the circumstances surrounding the loss of the ship should be made part of the official record. Many ship captains will actually insist on a court-martial in such circumstances.

Bradley Edward Manning (born December 17, 1987) is a United States Army soldier who was arrested in May 2010 in Iraq on suspicion of having passed classified material to the whistleblower website, WikiLeaks. He was charged over the following months with a number of offenses, including communicating national defense information to an unauthorized source, and aiding the enemy, a capital offense, though prosecutors said they would not seek the death penalty.

Assigned as an intelligence analyst in October 2009 to an army unit based near Baghdad, Manning was given access to several databases used by the United States government to transmit classified information. He was arrested after Adrian Lamo, a computer hacker, told the FBI that Manning had confided during online chats that he had downloaded material from these databases and passed it to WikiLeaks. The material, much of it published between April and November 2010, included videos of a 2007 helicopter gun attack in Baghdad and the 2009 Granai airstrike in Afghanistan, 250,000 United States diplomatic cables, and 500,000 army reports that came to be known as the Iraq and Afghan War logs. It was the largest set of restricted documents ever leaked to the public.

Phil Silvers (May 11, 1911 – November 1, 1985) was an American entertainer and comedy actor, known as "The King of Chutzpah." He is best known for starring in The Phil Silvers Show, a 1950s sitcom set on a U.S. Army post in which he played Sergeant Bilko.

Born Philip Silver on Thursday, May 11, 1911, in Brooklyn, New York, in the working-class Brownsville section, he was the eighth and youngest child of Russian-Jewish immigrants, Saul and Sarah (née Handler) Silver. His siblings were Lillian, Harry, Jack, Saul, Pearl, Michael, and Reuben Silver. His father, a sheet metal worker, helped build the early New York skyscrapers.

Silvers started entertaining at age 11, when he would sing in theaters when the projector broke down (a common occurrence in those days). By age 13 he was working as a singer in the Gus Edwards Revue, and then worked in vaudeville and as a burlesque comic.

Silvers next worked in short films for the Vitaphone studio, such as Ups and Downs (1937), and on Broadway, where he made his debut in the short-lived show Yokel Boy in 1939. Critics raved about Silvers, who was hailed as the bright spot in the mediocre play. The Broadway revue High Kickers (1941) was based on his concept.

Robert John Wagner (born February 10, 1930) is an American actor of stage, screen, and television, best known for starring in the television shows It Takes a Thief (1968–70), Switch (1975–78), and Hart to Hart (1979–84). In movies, Wagner is known for his role as Number Two in the Austin Powers films (1997, 1999, 2002). He also had a recurring role as Teddy Leopold on the TV sitcom Two and a Half Men.

Wagner's autobiography, Pieces of My Heart: A Life, written with author Scott Eyman, was published on September 23, 2008.

Wagner was born in Detroit, Michigan. He is the son of Hazel Alvera (née Boe), a telephone operator, and Robert John Wagner Sr., a traveling salesman who worked for the Ford Motor Company. His paternal grandparents were born in Germany. Wagner has a sister, Mary. He graduated from Santa Monica High School in 1949.

He made his film debut in The Happy Years (1950). He was signed by agent Henry Willson and put under contract with 20th Century-Fox, where he gained attention with a small but showy part as a shellshocked soldier in With a Song in My Heart (1952). This led to star roles in a series of films including Beneath the 12-Mile Reef (1953) and Prince Valiant (1954), and White Feather (1955, with Debra Paget and Jeffrey Hunter), A Kiss Before Dying (1956, a rare villainous role) and Between Heaven and Hell (1956).

George Armstrong Custer (December 5, 1839 – June 25, 1876) was a United States Army officer and cavalry commander in the American Civil War and the Indian Wars. Raised in Michigan and Ohio, Custer was admitted to West Point in 1858, where he graduated last in his class. However, with the outbreak of the Civil War, all potential officers were needed, and Custer was called to serve with the Union Army.

Custer developed a strong reputation during the Civil War. He fought in the first major engagement, the First Battle of Bull Run. His association with several important officers helped his career, as did his success as a highly effective cavalry commander. Custer was eventually promoted to the temporary rank (brevet) of major general. (At war's end, he reverted to his permanent rank of captain.) At the conclusion of the Appomattox Campaign, in which he and his troops played a decisive role, Custer was on hand at General Robert E. Lee's surrender.

After the Civil War, Custer was dispatched to the west to fight in the Indian Wars. His disastrous final battle overshadowed his prior achievements. Custer and all the men with him were killed at the Battle of the Little Bighorn in 1876, fighting against a coalition of Native American tribes in a battle that has come to be popularly known in American history as "Custer's Last Stand".
