Army Rank Flags (Taiwan)

Just happened to find the ROC (Taiwan) Army Flags Regulations on Wikisource, as enacted on April 24, 1953, and abolished on December 17, 1985.

To summarize:

The Army flag was in the proportions of 7:8 [since officially changed to 2:3], red field with a blue rectangle, 1/4 the total area of the flag, bearing a white sun, at the centre;

The Army Commander-in-Chief flag had additional yellow border and fringe, topped with a small blue-white-red tricolour bearing a yellow plum blossom (shown in Flags Through the Ages and Across the World [smi75b);

The Army Vice Commander-in-Chief flag had additional yellow fringe (but not border), topped with a small red rectangular flag bearing a yellow plum blossom;

Corps/Division/Brigade Command; Airborne/Armoured Branch; Garrison Command; Corps/Division Military District all had their army flag topped with a small yellow triangular flag (right angled at the lower hoist, as per the pre-1890 Chinese National Flag) bearing one or two ideograms in black as a kind of initials to indicate the level of command;

Army Hospitals and Sanitary Units had their army flag topped with a small white rectangular flag bearing a red cross;

Regiments and lower units had their army flag topped with red tassels, and with unit name in black on a white stripe near the hoist;

Army schools' flag had the sun inside a circle rather than a rectangle, and with yellow fringes.

Commander-in-Chief

In May 6, 1953, a flag similar to the National Revolutionary Army Commander-in-Chief was created in Taiwan for the position of Commander-in-Chief. It was again based on the Army flag, but with a yellow border on all four sides, and was further fringed in yellow. Above it was a small blue-white-red horizontal tricolour with a yellow plum blossom at its centre. Like all other Taiwanese military flags, it was carried on a red pole with white metal spearhead finial and white metal pike base.

Rank Flag Information

The Taiwanese Army rank flags are green, with the Army emblem above yellow five-pointed stars arranged horizontally: General First Class has four, General Second Class has three, Lieutenant-General has two, Major-General has one. That of colonel has thee plum blossoms in place of stars.

The Army emblem consists of crossed rifle and sword, surrounded by two panicles of rice, each containing seven grains (representing July 7, the beginning of Sino-Japanese War in 1937), the whole under the white sun on blue disc.
