Sergeant (normally abbreviated to Sgt) is a rank used in some form by most militaries, police forces, and other uniformed organizations around the world. Its origins are the Latin serviens, "one who serves", through the French term Sergent.

In most armies^{[clarification needed]} the rank of sergeant corresponds to command of a squad (or section). In Commonwealth armies, it is a more senior rank, corresponding roughly to a platoon second-in-command. In the United States Army, sergeant is a more junior rank, corresponding to a four-man fireteam leader.

More senior non-commissioned ranks are often variations on sergeant, for instance staff sergeant, sergeant first class, master sergeant, first sergeant and sergeant major. The spelling serjeant is used in a few regiments of the British Army.

In most non-naval military or paramilitary organizations, the various grades of sergeant are non-commissioned officers (NCOs) ranking above privates and corporals, and below warrant officers and commissioned officers. The responsibilities of a sergeant differ from army to army. There are usually several ranks of sergeant, each corresponding to greater experience and responsibility for the daily lives of the soldiers of larger units.

Bowe Robert Bergdahl (born March 28, 1986, in Sun Valley, Idaho) is a United States Army soldier who, since June 2009, is in the captivity of the Taliban-supporting Afghanistan Haqqani network.

Bergdahl is assigned to the 1st Battalion, 501st Infantry Regiment, 4th Brigade Combat Team, 25th Infantry Division, based at Fort Richardson, Alaska. He went missing on June 30, 2009. Since then, the Taliban has released five videos showing him in captivity. The Taliban have demanded $1 million and the release of 21 Afghan prisoners and Aafia Siddiqui in exchange for Bergdahl's release. They have threatened to execute Bergdahl if Siddiqui is not released. Most of the Afghan prisoners are being held at Guantanamo Bay.

At the time of his capture, Bergdahl's rank was that of Private First Class (E-3). In June 2010, he was promoted to Specialist (E-4) during his absence. On June 17, 2011 he was promoted to the rank of Sergeant (E-5).

On July 18, 2009, the Taliban released a video showing they had captured Bergdahl. In the video, Bergdahl appeared downcast and frightened. A Department of Defense statement issued on July 19 confirmed that Bergdahl was declared "missing/whereabouts unknown" on July 1, and his status was changed to "missing/captured" on July 3.
