Origins The term "Aide-de-Camp' (ADC) is of French origin, meaning 'camp or field assistant'. The ADC was originally a military assistant in the field to a Sovereign, Chief of State, or General. They transmitted orders and supervised operations in the name of their commander, and even exercised delegated authority on occasions. In modern day, the ADC is an officer of the uniformed services who serves as a personal assistant to the President, Head of State, General, Admiral, or other high-ranking commanders. Compared to the military importance and tasks of ADCs in 19th Century armies, the role of ADCs today has changed to become mainly those of rendering personal assistance and acting as confidential secretaries to their commanders. In some countries, the ADC to the sovereign or Head of State is an honorary position. In others, ADCs have more detailed and important duties. In most countries, the tour of duty of an ADC is between two and four years, and it is usually required that an ADC appointee has served several years with troops previously. Role of the ADC The full-time ADCs to the President attend to the general administration, security and social needs of the President, and accompany the President at State functions, gatherings, ceremonies or occasions of ceremonial or charitable/social nature. They are responsible for the coordination, planning, implementation and follow-up of all of President’s events, both locally and overseas. Honorary ADCs assist the full-time ADCs to perform their duties in serving the President. They help in areas such as receiving guests and serving as liaison officers for VIPs or as emcees at official events. Their assistance facilitates the smooth running of these functions. Our ADCs Three full-time ADCs serve the President of the Republic of Singapore. They are assisted by a corps of Honorary ADCs from the Singapore Armed Forces, the Singapore Police Force and the Singapore Civil Defence Force at events. The AiguilletteInternationally, ADCs may be identified by the aiguillettes worn across their right shoulder. The aiguillettes are plaited cords ending at two points called aglets. Historically, the aglets were used by knights to fasten the plates of their armour together. Aiguillettes are worn on the right shoulder by only officers of certain appointments, namely:Chief of Defence Force in the Singapore Armed ForcesCommissioner of Police in the Singapore Police ForceCommissioner in the Singapore Civil Defence ForceAides-de-Camp to the PresidentHonorary Aides-de-Camp to the PresidentIn Singapore, ADCs from the Singapore Armed Forces and the Singapore Civil Defence Force wear gold aiguillettes, while those from the Singapore Police Force wear silver aiguillettes.
