Identity provenance
Service ensign: Army Flag of the Republic of China — carried by ROC Army, not issued to this record. The Army flag: a red field charged with a navy rectangle bearing the white sun of twelve rays, 2:3 — the National Revolutionary Army's flag, carried by the Army since. The design was verified independently of the file: the Armed Forces Flags Act and the vexillological record both give a red field with the blue-sky white-sun panel at the centre, which is what this file draws. FILE: Wikimedia Commons "Flag of the Republic of China Army.svg", public domain, with the ROC Ministry of National Defence recorded as the author of the original. 377 bytes, three paths and two transforms; nothing was optimised because there was nothing to remove. Inherited by every corps and defence command below.
State affiliation: Taiwan.
The smaller square mark is a Vigil category device, drawn from this record’s own domain, echelon and role — not an official insignia.

- Notable history
- The southern of the ROC Army's three standing corps, designated the Fourth Theatre of Operations in the reorganisation effective 1 January 2022. Its area contains the island's largest port and the southern end of the western coastal plain — the part of Taiwan's west coast that published landing analysis returns to most often, because it is where suitable beaches and the road network behind them coincide. The command also sits at the northern end of the Bashi Channel problem: the waters between southern Taiwan and Luzon are where the maritime and air approaches from the Philippine Sea converge, and they are the same waters the Philippine Northern Luzon Command looks north across.
- Strengths
- Covers the island's principal southern port and industrial region with a standing joint theatre command, and shares a theatre boundary with the naval and air structures whose main southern establishments lie in the same region.
- Limitations
- The same coastal geography that makes the area defensible in depth also makes it the part of Taiwan most frequently modelled as a landing area by outside analysts, and this module publishes no assessment of any such scenario. No subordinate units, dispositions, strengths or readiness are recorded here.
