The regiment is divided into three battalions, all of them based in Bangkok. The regiment is the only unit of the Royal Thai Armed Forces with the designation Mahat Lek Rajawallop (Thai: มหาดเล็กราชวัลลภ); meaning the king's close bodyguards, translated as the King's Own Bodyguards. The unit was first established by King Chulalongkorn (Rama V) in 1859, whilst he was still a young prince. One of the primary role of the regiment is to provide security and protection to members of the Thai royal family as well as the ceremonial escort and guarding of the royal palaces.
