The military ranks of Thailand are the military insignia used by the Royal Thai Armed Forces. The officer ranks are influenced by the ranks of the United Kingdom and United States, while the non-commissioned ranks are influenced by those of the United Kingdom and France.^[1]

Private 1st class is a rank assigned to conscripts after they have finished specialist training. They wear the same insignia as a lance corporal, who is a member who has completed his conscription obligation, and who has undertaken training at NCO school.

The rank of "Special Sergeant Major 1st Class" (Thai: จ่าสิบเอกพิเศษ, romanized: Cha Sip Ek Phiset) is an honorary rank given to senior enlisted members who are deserving of recognition above and beyond that of the highest enlisted rank. There is no difference in the rank insignia worn, and they do not outrank the normal master sergeant 1st class, although in a group situation they will normally be assigned control. They receive a higher salary. In the same way, the RTN has the rating of "fleet chief petty officer (special rank)" and the RTAF has the rank of "special flight sergeant 1st class".^{[citation needed]}

Royal Thai Navy

The Royal Thai Navy is the sea-based part of the Thai military. The Royal Thai Marine Corps is part of the RTN, and uses the same rank structure. Depending on the uniform, the rank insignia can be located on the shoulder (on white and khaki uniforms) or on the sleeves (on dark blue uniforms).

Royal Thai Air Force

The Royal Thai Air Force (RTAF) (กองทัพอากาศไทย, RTGS Kong Thap Akat Thai, IPA: [kɔːŋ tháp ʔaːkàːt thaj]) is the air based part of the Thai military. The rank system is modelled after that of the British Royal Air Force (RAF), but unlike the RAF, officers' cuff rank insignia are topped by a star above the lace stripes and all air marshals' rank insignia are also determined by one to five stars on the shoulder board.

Royal Thai Police

The Royal Thai Police (RTP) is sometimes considered as the fourth armed service of Thailand (๔ เหล่าทัพ), but reports directly to the Prime Minister's Department rather than to the Ministry of Defense. The Royal Thai Police share the same rank system as the Royal Thai Army but the particularities of the police are the star representing the commissioned officer and the crown over the star. The Royal Thai Police uses the eight-pointed silver star and the silver crown with a halo on top, while the Royal Thai Army uses the five-pointed gold star and the gold crown with no halo for its officer shoulder boards.
