Royal Security Command
The Royal Security Command () is The king of Thailand’s military household and is part of Thailand’s royal court administration.  It exercises command and control over the military units that are engaged full-time in the protection and guarding of the king and his family as well as the various Royal palaces of Thailand.

The command is responsible for the planning, direction and coordination of the security detachments of the king, queen, heir-apparent and other members of the Thai royal family. It is also responsible for the security of the monarch's representatives and visitors. The security and safety of the king, his family and Royal palaces are the direct responsibility of the Monarch. The units and personnel of the royal security command do not form part of the regular armed forces chain of command.

History

The Royal Security Command was formerly an agency under the Office of the Supreme Commander of the Royal Thai Armed Forces Headquarters. It was established as a King's Guard unit on 18 November 1992. In 2013, the Royal Security Command became a juristic person and was put under the purview of the Ministry of Defense while retaining Crown Prince Vajiralongkorn as its commander.

On 1 May 2017 the Royal Security Command was made a royal agency directly under the command of the monarchy, independent of the rest of the armed forces and the Royal Thai Government.

On 30 September 2019, two infantry regiments were removed from the Royal Thai Army's chain of command and placed under the Royal Security Command. All personnel, assets and operating budgets were likewise transferred to the agency. The move was prompted by the need to provide better security to the royal family, royal residences, and Foreign heads of state and other dignitaries dignitaries visiting at the monarch's invitation.
