Role

The Royal Thai Armed Forces primarily aim to protect the sovereignty and territorial integrity of Thailand. Their duties include defending the Thai monarchy against all threats, maintaining public order, and assisting in national disaster relief and drug control. Additionally, they support social development by cooperating with civilian government initiatives. There are differing perspectives on the roles of the Thai armed forces. While their official duties are well-defined, some critics argue that their functions extend to preserving ruling class hegemony against democratic movements and facilitating the self-enrichment of high-ranking military officials The Royal Thai Armed Forces have also played a role in international peacekeeping efforts. Notably, they contributed to the

Additionally, they were part of the multinational force in Iraq, contributing 423 personnel from 2003 to 2004. This international involvement reflects their expanding role beyond national borders.


Personnel

, the Royal Thai Armed Forces (RTARF) comprised approximately 360,850 active duty and 200,000 reserve personnel, which is nearly one percent of Thailand's population of 70 million. This proportion of military personnel in relation to the total population is higher than that of the United States but lower than Vietnam's. The Thai military includes over 1,700 flag officers (generals and admirals), equating to about one general for every 212 troops. This ratio is notably higher than that of the United States military, which as of November 1, 2018, had 920 active duty general and flag officers for a force of 1,317,325 personnel, resulting in one flag officer for every 1,430 troops. On May 2, 2015, 1,043 new flag officers from all three services of the Thai military were sworn in. The number of officers who retired during the same period is not specified. Observations by some analysts suggest that the goals of Thai generals include aligning with politically favorable parties, securing advantageous postings, and personal enrichment, which reportedly involves sharing gains with subordinates to maintain loyalty. In early 2021, Thailand's Ministry of Defence announced a plan to reduce the number of flag officers by 25% by 2029. As of March 2021, the RTARF had about 1,400 generals and admirals: 250 at RTARF headquarters, 400 in the army, 250 in the navy, 190 in the air force, and 300 in the Office of the Permanent Secretary of Defence.


Conscription

Conscription, a national duty outlined in the Constitution of the Kingdom of Thailand, was initiated in 1905. It mandates military service for all Thai citizens, although in practice, it primarily applies to males over 21 years of age who have not completed reserve training. The annual

process, typically held in early April, begins with eligible individuals reporting to their selection center at 07:00 on the designated day. During this process, draftees have the option to volunteer for service or participate in a lottery if they do not volunteer. Those who choose to volunteer undergo thorough physical and mental health evaluations, including a drug test. The results of these drug tests are recorded in the Narcotics Control Board's database. In 2018, data showed that out of 182,910 men tested, 12,209, or 6.7 percent, tested positive for drugs, with the majority detected for

, and other substances. Individuals who test positive for drugs are subject to different treatments based on their conscription status. Over 3,000 men who tested positive and were drafted into the military received drug rehabilitation treatment as part of their service. Conversely, those who tested positive but were not drafted underwent a 13-day rehabilitation program in their home provinces. Candidates who do not meet the physical and mental health standards are exempted from service. Those who pass the examinations and volunteer for enlistment select their preferred service branch (Royal Thai Army, Royal Thai Navy, or Royal Thai Air Force) and a reporting date. They receive official documentation summarizing the draft selection of the year, along with an enlistment order detailing the specifics of their basic training, including the time and location. The process concludes for the day with the dismissal of the enlistees, who then await their reporting date for basic training. Following the dismissal of the volunteers, the conscription lottery commences at each selection center. The number of individuals conscripted via the lottery is determined by the center's set quota, minus the number of volunteers. Like the volunteers, those participating in the lottery undergo the same physical and mental health assessments, with ineligible individuals being similarly dismissed. During the lottery, each man draws a card from an opaque box. A black card signifies exemption from military service, and the individual receives a letter of exemption. Conversely, drawing a red card mandates military service, with the induction date specified on the card. Individuals with higher educational qualifications may request a reduction in their service obligation. In 2018, over 500,000 men were called for selection by the Royal Thai Armed Forces. The combined quota across the forces was approximately 104,000, including 80,000 for the Royal Thai Army, 16,000 for the
Royal Thai Navy The Royal Thai Navy (Abbreviation, Abrv: RTN, ทร.; , ) is the Navy, naval warfare force of Thailand. Established in 1906, it was modernised by the Admiral Prince Abhakara Kiartiwongse (1880–1923) who is known as the father of the Royal N ...

. On the selection day, 44,800 men volunteered for service. After accounting for these volunteers and those dismissed due to ineligibility, the remaining quota was approximately 60,000 slots. This quota was to be filled by the approximately 450,000 men participating in the draft lottery, making the overall probability of drawing a red card about 13 percent. In 2017, a total of 103,097 men participated in the military draft in Thailand, conducted from April 1 to 12. The armed forces required 77,000 conscripts annually. In some cases, certain selection centers did not need to conduct the balloting lottery because their quotas were already fulfilled by volunteers. In these instances, individuals who opted not to volunteer and instead waited for the lottery were issued certificates of exemption. The duration of military service in Thailand varies depending on whether an individual volunteers and their level of educational attainment. Volunteers are generally required to serve for shorter periods. Those without a high school diploma must serve for two years, irrespective of their volunteer status. High school graduates who volunteer are obligated to serve for one year, whereas those who do not volunteer and draw red cards during the lottery are required to serve for two years. Individuals holding an associate degree or higher and who volunteer have a six-month service period. Those with similar educational qualifications who draw red cards during the lottery may request a reduction in their service time, up to a maximum of one year. University students are permitted to defer their conscription until they have completed their degree or reached the age of 26. All conscripts in the Thai military are assigned the rank of Private, Seaman, or Aircraftman (OR-1), and they retain this rank throughout their service, regardless of their educational qualifications. Their wages are subject to increase after completing basic training and with time-in-grade. It is reported by some sources that a significant number of conscripts, over half according to these claims, are utilized as servants to senior officers or clerks in military cooperative shops. However, it is important to note that the placement of conscripts, irrespective of their volunteer status and educational background, is typically determined by the operational needs of their respective service branches. The most common roles assigned include

man for Royal Thai Army conscripts, Royal Marine for Royal Thai Navy conscripts, and security forces specialist for Royal Thai Air Force conscripts. Their duties can vary, encompassing military operations, manning security checkpoints, force generation, and performing manual labor or clerical tasks as required by their unit. Upon completing their service, conscripts are presented with the option to reenlist. In April 2020, for instance, only 5,460 out of 42,000 conscripts eligible for discharge at the end of the month chose to continue their service in the military. Top government officials in Thailand maintain that conscription is essential for the country. However, there is an ongoing debate regarding the necessity and effectiveness of conscription in 21st-century Thailand. Critics argue that, as of 2019, the external threats to Thailand are minimal. This perspective seems to align with Thailand's new National Security Plan, published in the Royal Gazette on November 22, 2019. Effective from November 19, 2019, to September 30, 2022, the plan suggests that external geopolitical threats are not significant in the forthcoming years, focusing instead on domestic issues, notably concerns about declining faith in the monarchy and political divisions. In September 2023, the

, in a report from March 2020, alleges that Thai military conscripts are subjected to institutionalized abuse, which is often overlooked by military authorities. The report describes this practice as a "long-standing open secret in Thai society". One notable case cited by Amnesty occurred in 2011, involving the death of Wichian Pueksom, allegedly due to torture by 10 officers. As of the report's publication, no verdict had been rendered in this case.


Budget

The defence budget nearly tripled from 78.1 billion baht in 2005 to 207 billion baht for FY2016 (1 October 2015 – 30 September 2016), amounting to roughly 1.5% of GDP. The budget for FY2017 is 214 billion baht (US$6.1 billion)—including funds for a submarine purchase—a nominal increase of three percent. The proposed budget again represents around 1.5% of GDP and eight percent of total government spending for FY2017. The FY2018 defence budget is 220 billion baht, 7.65% of the total budget. According to ''Jane's Defence Budgets'', the Royal Thai Army generally receives 50% of defense expenditures while the air force and navy receive 22% each. The Ministry of Defense budget for FY2021 is 223,464 million baht, down from 231,745M baht in FY2020.

After the Thammasat University massacre of leftist student demonstrators in 1976 and the repressive policies of right-wing Prime Minister Tanin Kraivixien, sympathies for the movement increased. By the late-1970s, it is estimated that the movement had as many as 12,000 armed insurgents, mostly based in the northeast along the Laotian border and receiving foreign support. By the 1980s, however, all insurgent activities had been defeated. In 1982 Prime Minister Prem Tinsulanonda issued a general amnesty for all former communist insurgents.

Thai–Laotian Border War (1987–1988)

This was a small conflict over mountainous territory including three disputed villages on the border between Sainyabuli Province in Laos and Phitsanulok Province in Thailand, whose ownership had been left unclear by the map drawn by the French some 80 years earlier. Caused by then-Army commander Chavalit Yongchaiyudh against the wishes of the government, the war ended with a stalemate and return to status quo ante bellum. The two nations suffered combined casualties of about 1,000.


East Timor (1999–2002)

After the East Timor crisis, Thailand, with 28 other nations, provided troops for the International Force for East Timor or INTERFET. Thailand also provided the force commander, Lieutenant General Winai Phattiyakul. The force was based in

Iraq War (2003–2004)

After the successful US invasion of Iraq, Thai Humanitarian Assistance Task Force 976 Thai-Iraq Thailand contributed 423 non-combat troops in August 2003 to nation building and medical assistance in post-Saddam Iraq. The Thais could not leave their base in Karbala as their rules governing their participation restricted them to humanitarian assistance which could not be accomplished due to the insurgency during the Thai's tenure in Iraq. Troops of the Royal Thai Army were attacked in the 2003 Karbala bombings, which killed two soldiers and wounded five others. However, the Thai mission in Iraq was considered an overall success, and Thailand withdrew its forces in August 2004. The mission is considered the main reason the United States decided to designate Thailand as a major non-NATO ally in 2003.Thailand

South Thailand insurgency (2001–ongoing)

The ongoing southern insurgency had begun in response to Prime Minister Plaek Phibunsongkhram's 1944 National Cultural Act, which replaced the use of Malaya in the region's schools with the Thai language and also abolished the local Islamic courts in the three ethnic Malay and

majority border provinces of Yala, Pattani, and Narathiwat. However, it had always been on a comparatively small scale. The insurgency intensified in 2001, during the government of Prime Minister Thaksin Shinawatra. Terrorist attacks were now extended to the ethnic Thai minority in the provinces. The Royal Thai Armed Forces also went beyond their orders and retaliated with strong armed tactics that only encouraged more violence. By the end of 2012 the conflict had claimed 3,380 lives, including 2,316 civilians, 372 soldiers, 278 police, 250 suspected insurgents, 157 education officials, and seven Buddhist monks. Many of the dead were Muslims themselves, but they had been targeted because of their presumed support of the Thai government.


Cambodian–Thai border stand-off (2008–2011)

Is an event that began in June 2008 over the border dispute with the Temple of Preah Vihear afterwards. There were many clashes between the two sides. Along with the claims of each party over the said dispute territory.


Sudan (2010–2011)

Thai soldiers joined UNMIS in 2011.


Current developments


Thai military deputized as police

On 29 March 2016, in a move that the ''Bangkok Post'' said will "...will inflict serious and long-term damage...", the NCPO, under a Section 44 order (NCPO Order 13/2559) signed by junta chief Prayut Chan-o-cha, granted to commissioned officers of the Royal Thai Armed Forces broad police powers to suppress and arrest anyone they suspect of criminal activity without a warrant and detain them secretly at almost any location without charge for up to seven days. Bank accounts can be frozen, and documents and property can be seized. Travel can be banned. Automatic immunity for military personnel has been built into the order, and there is no independent oversight or recourse in the event of abuse. The order came into immediate effect. The net result is that the military will have more power than the police and less oversight. The government has stated that the purpose of this order is to enable military officers to render their assistance in an effort to "...suppress organized crimes such as extortion, human trafficking, child and labor abuses, gambling, prostitution, illegal tour guide services, price collusion, and firearms. It neither aims to stifle nor intimidate dissenting voices. Defendants in such cases will go through normal judicial process, with police as the main investigator...trial will be conducted in civilian courts, not military ones. Moreover, this order does not deprive the right of the defendants to file complaints against military officers who have abused their power." The NCPO said that the reason for its latest order is that there are simply not enough police, in spite of the fact that there are about 230,000 officers in the

'' in 2014 called the Thai military one of the most deeply corrupt militaries in Asia. The Thai armed forces have a history of procurement scandals and dodgy dealings dating back to at least the 1980s. *In the 1980s, the army bought hundreds of substandard armored personnel carriers (APC) from the Chinese that were so shoddy that light was visible through the welds securing the armor plate. *The Thai air force bought Chinese jets with short-lived engines so delicate that the planes were towed to the flight line for takeoff and towed back on landing in order to minimize engine hours. *In 1997, the HTMS ''Chakri Naruebet'' aircraft carrier was commissioned. Due to its lackluster operational history, the Thai media have nicknamed the ship "Thai-tanic", and consider her to be a white elephant. *The Aeros 40D S/N 21 airship, nicknamed "Sky Dragon", was purchased for 350 million baht in 2009. It cost 2.8 million baht to inflate and 280,000 baht a month to keep inflated. It served for eight years, mostly in storage, and crashed once. The present leadership of the NCPO was instrumental in approving its purchase.


Weapons and equipment

Thailand's defense spending has soared since 2006. Since then the military has seized control from civilian governments on two occasions. Defense spending has increased by US$1 billion since the latest coup in 2014. In early January 2022, Thailand's cabinet backed a plan to buy four fighter jets starting in 2023 with 13.8 billion baht ($413.67 million) budgeted for the purchase over a 4 year period to replace some of the country's aging F-16 jets.


Uniforms, ranks, insignia

To build institutional solidarity and esprit de corps, each Thai service component has developed its own distinctive uniforms, ranking system, and insignia.Thailand
. Lcweb2.loc.gov. Retrieved on 18 January 2012.
Many Thai military uniforms reflect historical foreign influences. For example, most of the distinctive service uniforms were patterned on those of the US, but lower ranking enlisted navy personnel wear uniforms resembling those of their French counterparts. The early influence of British advisers to the Thai royal court and the historical role of the military in royal pomp and ceremony contributed to the splendor of formal dress uniforms worn by high-ranking officers and guards of honour on ceremonial occasions. The rank structures of the three armed services are similar to those of the respective branches of the US Armed Forces, although the Thai system has fewer NCO and warrant officer designations. The king, as head of state and constitutional head of the armed forces, commissions all officers. Appointments to NCO ranks are authorised by the minister of defence. In theory, the authority and responsibilities of officers of various ranks correspond to those of their US counterparts. However, because of a perennial surplus of senior officers—in 1987 there were some 600 generals and admirals in a total force of about 273,000—Thai staff positions are often held by officers of higher rank than would be the case in the US or other Western military establishments. Thai military personnel are highly conscious of rank distinctions and of the duties, obligations, and benefits they entail. Relationships among officers of different grades and among officers, NCOs, and the enlisted ranks are governed by military tradition in a society where observance of differences in status are highly formalised. The social distance between officers and NCOs is widened by the fact that officers usually are college or military academy graduates, while most NCOs have not gone beyond secondary school. There is a wider gap between officers and conscripts, most of whom have even less formal education, service experience, or specialised training. Formal honours and symbols of merit occupy an important place in Thai military tradition. The government grants numerous awards, and outstanding acts of heroism, courage, and meritorious service receive prompt recognition.
