Corps of Engineers Vessel Flag

image by Tom Gregg, 10 July 1998

Vessel Flag, Corps of Engineers. This flag is also authorized to be flown on land by Corps of Engineers facilities that are not located on Army installations.
Tom Gregg, 10 July 1998

It dates from the early part of this century. Originally intended for vessels it is now used by divisions, districts, laboratories, offices and facilities of that corps. See AR 840-10 Chapter 7-7 for full details.

Division Engineer Pennant

image by Joe McMillan, 28 May 2000

Engineer Regulation 840-1-1 provides that a division or district engineer may authorize the flying of a pennant to denote his or her presence aboard a vessel. Only one such pennant may be flown at a time; if the division and district engineers are both aboard the same vessel, only the division engineer's pennant is displayed. The pennants are 29 x 45 inches. If a general officer of the Army is aboard, his flag is flown instead of the division or district engineer's pennant.

Division Engineer pennant: vertical stripes of red (9 inches wide), white (15 inches wide), and blue, with a red Engineer castle measuring 7.37 x 12 inches centered on the white.

The colors are specified as Old Glory red (Cable #70180 on the Standard Color Card of America) and National Flag blue (Cable #70077).

Transportation Corps Vessel Flag

Vessel Flag, Transportation Corps, U.S. Army. Army-operated ships and watercraft fly branch-specific vessel flags in addition to the National Ensign. For some reason, they not only come in several sizes but in two different proportions: 4:5 and 2:3; I have illustrated the latter. Vessel flags are in branch colors, in this case brick red and golden yellow for the Transportation Corps. The insignia is the branch badge as worn on the lapels of the Class "A" uniform jacket by commissioned officers. Most Army vessels are operated by either the Transportation Corps or the Corps of Engineers, though AR 840-10 also illustrates a vessel flag for the Signal Corps.

Quartermaster Corps Vessel Pennant

image by Miles Li, 13 March 2009

U.S. Army: Quartermaster Corps Pennant (1923) Per the 1923 edition of AR 260-10, vessels operated by the Quartermaster Corps, other than ships of the Army Transport Service, flew a triangular red, white and blue pennant with the branch insignia of the Quartermaster Corps centered in the white diamond-shaped portion. This pennant was made of bunting in two sizes: 4-foot hoist by 6-foot fly and 2-foot hoist by 3-foot fly. This pennant is not described in the 1931 edition of the regulation, so it was apparently abolished at some prior time.
Tom Gregg, 9 March 2000

This pennant was shown twice on National Geographic Magazine Oct 1917, once as "Guidon Motor Truck Company", and once as "Army Supply Train".

Army Post Commander Pennant (circa 1910-1923)

image by Joe McMillan, 10 December 2000

Army Post Commander, circa 1910-circa 1923 - The commander of an army post below general officer rank was authorized to display a pennant in the bow of a boat in which he was embarked. This pennant was 1:3, the hoist (one-third the length of the fly) blue with thirteen white stars in rows of 4, 5, and 4, the remainder scarlet. This pennant was prescribed in the 1910 and 1913 Army Regulations and appears in [gmc17] but is not provided for in the 1923 AR 260-10.

I used the current Army Ordnance Corps emblem as an outline template for my image, therefore it differs from the NGM illustration in minor artistic details.

Commission Pennant

This seems to amount to the Naval Commissioning pennant with two colours exchanged.
