The Royal Thai Police (RTP) is the national police force of Thailand. The RTP employs between 210,700 and 230,000 officers, roughly 17 percent of all civil servants. The RTP is frequently recognized as the fourth armed force of Thailand since their tradition, concept, culture, skill, and training are relatively similar to the army and most of their officer cadets need to graduate from the Armed Forces Academies Preparatory School before entering the Royal Thai Police Cadet Academy. Officers also undergo paramilitary training similar to the army but with an additional focus on law enforcement.
