Territorial defense students (Thai: นักศึกษาวิชาทหาร; RTGSnak sueksa wicha thahan) are a military youth organization in Thailand under control of the Royal Thai Army, and recently the Royal Thai Navy and Royal Thai Air Force.


Colours of Provincial "Yuwachon Thahan" unit, a Thai military youth organization in 1934-1947.

Prior to World War II the Yuwachon Thahan (or "junior soldiers", Thai: ยุวชนทหาร) or more commonly referred to as Territorial Defense (Thai: รักษาดินแดน, shortened as ร.ด. in Thai) were established in 1934 by Field Marshal Luang Pibulsonggram. At the beginning of World War II junior soldiers were sent to fight troops of the Japanese Empire that invaded southern Thailand on 8 December 1941.[citation needed]

At the end of the war the junior soldiers were disbanded, but Lieutenant General Luang Chatnakrop (พล.ท. หลวงชาตินักรบ) created the territorial defense students to replace them in 1948.

Battle of Tha Nang Sang Bridge[edit]

Battle of Tha Nang Sang Bridge in 8 December 1941 between the Imperial Japanese Army and Thai forces, consist of officers from the Royal Thai Army, Thai policemen and Thai junior soldiers, at Chumphon Province, Thailand.(Diorama at National Memorial)

On the first day of the Japanese invasion of Southeast Asia (8 December 1941), the Japanese Army sent troops to many parts of Chumphon Province. At Ma Hat Bay, the Japanese forces landed on beaches stretching from Ban Pak Nam Chumphon to Ban Kho Son. The 38th Infantry Battalion of the Royal Thai Army, about 17 km away, was too far away to intercept the initial invaders in time. As a result, roughly 100 of the reserve students and the local police force had to hold the numerically superior Japanese army at bay from positions on the west side of Tha Nang Sang Bridge until the 38th Infantry could arrive.

The force of reserve students and policemen sent their 1st Light Machine Gun Company across the bridge at 08:00. They then went through Wat Tha Yang Tai to block any Japanese reinforcements. The commander of 38th Infantry wished to send his 4th Heavy Machine Gun Company across the bridge to protect the government buildings on the Tha Taphoa River, but the Japanese troops fired upon the Thai defenders from the other side of the river. The reserve students, under command of Captain Thawin Niyomsen, commander of the Chumphon Junior Soldiers Training Centre, charged cross the bridge to seize strategic points on the east side. Under heavy Japanese fire, Captain Thawin was killed when he attempted to find a new position for his light machine gun squad. The remaining students, now headed by Sergeant Samran Khuanphan from the training centre, were able to maintain their position, and waited for friendly reinforcements. Thailand, however, surrendered to Japan before noon.[1]

Uniform and insignia[edit]

Uniform of the territorial defense student. (since 2014)

Army territorial defense students wear a khaki-green uniform and beret with the Army Reserve Command Insignia (Crossed swords under The Great Crown of Victory) on their collar, beret, and belt. Territorial defense students distinguish their school and province by the school's coat of arms on the right shoulder, and provincial badge on left breast. The name badge is sewn on the right chest.

Training years and rankings[edit]

Each student's training year can be distinguished by rectangular Thai Numeral ranging from 1 to 5 on a khaki-background tag. For command students, they are distinguished with colored background and pentagonal-shaped number tag. The official colorings are as follow.[3]

  • "Green": Platoon Leader
  • "Red": Company Leader
  • "Light Blue": Leader of Students(equivalent rank of Battalion leader)

In practice, the command student's ranking can go up to battalion or even regiment. These off-document ranks employ off-document insignia such as armbands with text notation. Such notations can also be employed for lower positions, as command students do not inherit their status into the Field Training.

Special training[edit]

About 120 fourth grade territorial defense students who pass the physical test are allowed to enter the parasail training course. Requirements are, for males, 15 pull-ups with no time limit, 47 push-ups in two minutes, 65 sit-ups in two minutes, and a one-mile run in eight minutes. Female applicants have more relaxed requirements.[citation needed]
