Thai Army Cadets in School: Uniform, Drill, and the Draft Talk

Army Cadets in Thai Schools | Ror Dor Days and Camps
Army Cadets in Thai Schools : Ror Dor (รด.) : Drill Days, Camp Weeks & Catch-Up Work
Teacher Life : By Matthew John

Ror Dor:
Fatigues on Drill Day, Catch-Up After Camp

We see it every term in the secondary schools we work with around Ban Lum: on a Thursday or Friday, some of your M4 to M6 students turn up in green fatigues and boots. They're Ror Dor cadets (รด.). They have class in the morning, drill in the afternoon, and after camp weeks they come back tired and behind. Your job is attendance and homework, agreed with your Thai co-teacher. The draft belongs to the Ministry of Defence, not to you or to us.

What Is Ror Dor? Reserve Training for M4–M6

Who joins, and why it matters for your timetable.

Voluntary (สมัครใจ)

Reserve Training Students

Ror Dor stands for naksueksa wicha thahan (นักศึกษาวิชาทหาร), shortened on paper to นศท. It is voluntary army reserve training for students from Mathayom 4 to 6 (and in some vocational colleges): drill, basic military skills and camps, alongside normal school. Younger students do scouts and guides instead.

M4 to M6 (ม.๔ - ม.๖)

Joining Up

Students usually sign up at the start of M4 and have to pass a fitness test to join. Not everyone in a class will be a cadet, so on drill day you may teach a half-empty room.

Girls Too (รด. หญิง)

Open to Girls

Girls can join Ror Dor (you'll hear รด. หญิง, ror dor ying) and do the drill and camps. They are not part of the male draft, so for them it is simply a choice.

Drill Day: Fatigues, Boots & the Afternoon Bus

Item & Thai What It Usually Looks Like What It Means for You
Fatigues
ชุดฝึก
Green or camouflage fatigues with a school or unit patch. Details vary. Cadets wear it all day, including your morning lesson. Rooms get warm, so open windows or use the fans.
Combat boots
รองเท้าคอมแบท
Black lace-up boots. If your room is shoes-off, unlacing and relacing takes time. Allow a few minutes.
Belt & beret
เข็มขัดสนาม และ หมวกเบเรต์
Web belt, with a beret or cap. Headwear comes off indoors; let students put it away.
Short haircut
ผมเกรียน
Usually very short, as the trainers require. Don't comment on it. It goes with the kit.
Morning

Class in the Morning

Drill day often runs to a split timetable: cadets come to morning lessons in uniform, then take a bus to the local army base (มทบ., monthon thahan bok) or training site for drill in the afternoon. Times and days vary by school; Thursday or Friday is common, so check the LINE group.

Afternoon

A Half-Empty Room

If you teach M4 to M6 in the afternoon on drill day, the cadets will be away and everyone else stays. Use the lesson for review, pair speaking or project work, not new material the cadets will need for a test.

Camp Weeks: Khao Chon Kai and Tired Kids

What camp means for your classes. Dates vary by school and year.

Years 1 & 2

Field Training Camps

Cadets in Years 1 and 2 usually go on field training (fuek phak sanam, ฝึกภาคสนาม) at an army site. Dates vary by school and year, so watch the Thai school calendar and the LINE group.

Year 3

Khao Chon Kai

Year 3 cadets (usually M6) are known for their camp at Khao Chon Kai in Kanchanaburi, the best-known Ror Dor training site. Ask your co-teacher which week it falls in; don't rely on dates you read online.

After Camp

Catch-Up After Camp

Cadets come back tired and behind. Agree catch-up work (ngan chot-choei, งานชดเชย) and any make-up speaking tests with your Phee Liang, and follow the school's approach to absences.

The April Draw: What Students Talk About

The short version, as it is commonly explained. Explaining it is not your job.

Around Age 21

The April Draw

Thai men are called up around age 21, and selection day, usually in early April, is often decided by drawing cards. It's a big day for families, and your students will talk about it.

Black Card

Bai Dam (ใบดำ)

As it is commonly explained, drawing a black card (bai dam, ใบดำ) means not being selected for active service that year.

Red Card

Bai Daeng (ใบแดง)

A red card (bai daeng, ใบแดง) means being selected for military service. Service length is commonly described as up to two years, shorter for some volunteers; check current Ministry of Defence rules.

Three Years of Ror Dor and the Draft

You'll hear students say, "If I finish Ror Dor Year 3, I don't have to draw." Finishing three years is commonly described as a route onto the reserve list instead of the April draw, which is why many boys stick with it. But the rules are set by the Ministry of Defence and can change, and the paperwork is handled by the school and the district office, not by you. If a student asks, send them to the school's Ror Dor teacher. Your part is attendance and homework.

Your Job: Attendance and Homework

What we tell every KET teacher with M4 to M6 classes.

Deadlines & Marks

Ask Your Phee Liang First

Don't announce deadline extensions or change marks on your own. Ask your Phee Liang (พี่เลี้ยง, Thai co-teacher) how the department handles cadet absences, and treat every cadet the same way.

Energy

Plan for Tired Afternoons

After drill or camp, cadets are drained. Skip long lectures and heavy reading; use pair dialogues, vocabulary games and short speaking tasks.

In Class

Use Their Leadership

Cadets are used to line-ups and squad jobs. Make them team captains or give them classroom jobs; most take it seriously.

Respect

No Cadet Kit, No Drill Photos

Wear your normal smart work clothes, never cadet kit or borrowed badges, even as a joke. Don't photograph drills for your personal social media, and don't mock the uniform or the army.

💬 LINE Messages for Your Co-Teacher

Copy these to your Thai co-teacher or the department LINE group when planning around drill days. They end in คะ / ค่ะ; men can swap in ครับ.

Checking drill days: "ครูคะ นักเรียน ม.๕ ไปฝึก รด. วันไหนบ้างคะ? พอดีจะนัดสอบเก็บคะแนนค่ะ" (Which days do the M5 students go to Ror Dor drill? I need to schedule our speaking quiz.)
Checking camp week: "นักเรียน ม.๖ จะไปเข้าค่ายเขาชนไก่สัปดาห์ไหนคะ? จะได้เตรียมงานชดเชยให้ค่ะ" (Which week are the M6 students going to Khao Chon Kai? I'll prepare make-up work for them.)
Before moving a deadline: "ถ้านักเรียนไปฝึก รด. ขอเลื่อนส่งงานได้ไหมคะ? อยากทำตามแนวทางของโรงเรียนค่ะ" (If a student is away at Ror Dor drill, can they hand work in late? I want to follow the school's approach.)

Frequently Asked Questions

What is Ror Dor in Thai schools?
Ror Dor (รด.) is short for Naksueksa Wicha Thahan (นักศึกษาวิชาทหาร), voluntary army reserve training for students in Mathayom 4 to 6. Cadets do drill, basic military training and camps alongside their normal studies. Boys and girls can join.
What days do students wear cadet uniforms to school?
It varies by school, but Thursday or Friday is common. Cadets often have class in the morning in uniform, then take a bus to the local army base (มทบ.) for drill. Check your school LINE group.
What is the April draft lottery?
As it is commonly explained, Thai men called up around age 21 draw a card in April: a black card (ใบดำ, bai dam) means not selected, and a red card (ใบแดง, bai daeng) means military service. Details change, so check current Ministry of Defence rules.
Does three years of Ror Dor mean no draft?
Finishing three years of Ror Dor is commonly described as a route onto the reserve list instead of the April draw. The rules are set by the Ministry of Defence and can change, and the paperwork is handled by the school and the district office. It isn't something teachers need to explain.
How should foreign teachers handle homework and attendance for cadets?
Ask your Phee Liang (Thai co-teacher) before changing any deadline or mark. Record attendance the way the school does, give catch-up work after drill days and camp weeks, and expect tired students.
Can girls join Ror Dor?
Yes. Girls can join Ror Dor voluntarily and do the training and camps, but they are not part of the male draft.
