Structure of Royal Joseon Armed Forces

Unit Types

• Military District: The only time the Military District was organized was during World War II. During World War II, one Military District in Joseon included 1.5 million troops.

• Field Army: Field Army is a unit that is temporarily organized when necessary. It consists of 3-4 Corps.
• Corps: One corps contains 5-6 divisions or equivalent subunits. Each corps includes support brigades in addition to the subsidiary divisions.

• Brigade: The minimum unit for independent operations. One brigade consists of 4-8 battalions.
• Regiment: It's a unit smaller than a brigade and larger than a battalion. A regiment typically consists of 2,000-1,600 soldiers. Fewer soldiers belong to the regiment, which is classified as a support unit.
• Group: A group is a unit consisting mainly of special forces or support units, not frontline combat units. The number of troops in the group is fluid, ranging from 1000 troops to a group of up to 3200 troops.
• Battalion: One battalion consists of approximately 400 troops. It typically includes three combat companies and one support company.
• Company: One company consists of 3 platoons.
• Platoon: One platoon consists of three squads. for tanks, 4 tanks make up one platoon.
