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.
In brief
The army command for eastern Taiwan — the side of the island behind the mountains, and the side PLA activity has been moving toward since 2022.

- Eastern Taiwan — the Hualien and Taitung coastal strip east of the central range
- Notable history
- Designated the Second Theatre of Operations in the reorganisation effective 1 January 2022. The eastern coast has always been the strategically unusual part of Taiwan: separated from the population centres by a mountain range, thinly connected by road and rail, and for decades treated as the depth into which the island's air power and command arrangements could fall back. That assumption is what has changed. From the August 2022 exercises onward, PLA naval and air activity east of the island — and from 2026, standing China Coast Guard patrols in the same waters — has been the single most consistent trend in the pressure baseline. A theatre that was designed as a rear area is being treated by the other side as an approach.
- Strengths
- Terrain that is genuinely difficult to move through and easy to defend at the few points where movement is possible, and hardened infrastructure built into the mountains over decades.
- Limitations
- The theatre depends on lateral communications across the central range that are few and well known, and its assumed value as depth is precisely what the shift of activity to the eastern approaches has called into question. Vigil records that shift as reported activity and publishes no unit locations, facility detail, strengths or readiness for this command.

Key events
A coast guard task group is rotated east of Taiwan
Until June 2026 China Coast Guard activity in waters east of Taiwan had occurred only within announced military exercises. In June a task group led by the cutter Daishan began patrols there, described by the coast guard as law enforcement including vessel inspection, fishery protection and rescue. On 4 July a second task group led by the cutter Xiushan replaced it and continued the patrols, with the service stating it would strengthen law enforcement in what it called China's jurisdictional waters. Taiwan's authorities reject the characterisation. The rotation drew statements of concern from regional governments.
