In a military context, a command is a collection of units or a group of personnel under the control of a single officer. A command is usually a high-level formation which is responsible to government or the one of the senior officers in charge of a nation's military. A command is sometimes led by a Commander-in-Chief.

The Royal Navy has historically been split into several commands. There now remain only two commands, Fleet and Naval Home Command. It is planned that these two commands will soon amalgamate.

The modern British Army has only one named command, Land Command.

Although the concept of a command dates back to the foundation of the Royal Air Force, the term command (as the name of a formation) was first used in purely RAF-context in 1936 when Bomber Command, Fighter Command, Coastal Command and Training Command were formed. Since that time the RAF has made considerable use of the term. Currently, the RAF has two commands; Strike Command and Personnel and Training Command. These two commands will soon be co-located.
