7 - Agency Identification.

  1. The identification legend "U. S. Army" will be marked on all vehicles and equipment within the scope of this bulletin unless otherwise specified.
  2. The legend will be applied in letters 3 inches high. Smaller letters may be used only when the vehicle or equipment design is such that space at the marking location is limited and will not accept 3-inch size.
  3. This marking will be applied at the following locations. For vehicles and equipment, where design configuration does not coincide with the examples, the terminology "appropriate surfaces" is included, and is intended to complete legend location instructions. Location examples as shown in succeeding paragraphs are mandatory.
    1. Trucks (figure 2).
      1. At side edges of the hood, each side of the truck.
      2. Across cargo truck tailgates, across flat body rear sills, below rear cab window on truck tractors (above if required due to space limitation) across rear of van bodies or tank trucks, or another appropriate rear surface of other body types.

  4. Vehicles or equipment not already marked per this bulletin will be marked with the identification U. S. Army on all sides when intended for photographing or public display.

8 - Registration Numbers.

  1. Registration numbers will be marked on all vehicles and equipment to which such numbers are assigned, as defined in AR 700-10.
  2. The registration number marking will be applied immediately below the agency identification with a space of 2 inches between the two, where space permits. Normally, the registration number is applied directly below the agency identification on the sides of the vehicle or equipment. Refer to figures 2 through 8.
  3. The registration number will be applied directly in line with and to the right of the agency identification if this arrangement is more suitable because of location and space restriction. Normally, the registration number is marked to the right of the agency identification on the rear of the vehicle or equipment and on
    frame rail surfaces. Refer to figures 2 through 8.
  4. The registration number marking will be applied in the same colour, size, and method as the agency identification.

9 - Unit Identification.

  1. These markings will be applied to vehicles and equipment by units to which they are assigned. The markings will be maintained at all times but will be removed when the vehicle or equipment is permanently transferred.
  2. The unit identification markings will normally appear on both the front and rear of each vehicle, usually on vehicle bumpers when the vehicle is so equipped. Other suitable surfaces, front and rear, may be used provided the unit identification marking does not conflict with the location and legibility of other markings. Where no suitable surface is available at the front or rear, the markings will be applied in an appropriate location on each side of the vehicle. If necessary, the unit identification may be applied to the vehicle mounted equipment. Refer to figures 2 through 8.
  3. The markings will be of uniform letters and numerals of the largest size practical to use. They will not exceed the size of the registration number if on the same surface. In no case will the unit identification markings exceed 4 inches in height. Symbols used will be approximately the same size and stroke widths as the letter and numeral characters.
  4. The unit identification markings will be applied with a gasoline soluble paint or removable vinyl markings. The markings will be applied in colours as prescribed in paragraph 5e.

10 - Operational Markings.

  1. Tactical Markings. These markings are used to provide a more visible means for identifying vehicles of tactical units by the personnel of those units during tactical operations. Commanders of major organisations are responsible for determination of the type of tactical markings to be used by all units within their organisations, and the location of the markings on the vehicles. Changes may be made only with the approval of the major commanders.
    1. These tactical markings may consist of stripes, geometrical figures, or other simple designs, including names for individual vehicles.
    2. The markings will be of suitable size for identification from the ground at reasonable distances, and may be applied in any appropriate colour using gasoline soluble paint or removable vinyl markings.
    3. Tactical markings should be designed to be as nearly unintelligible to enemy observation as possible. The markings will not, in any way, represent or suggest the numerical designation or distinctive insignia of any unit. No written record will be made or published describing the system of markings used.
  2. Priority Sign. This is a sign to mark those vehicles which are assigned priority of movement over all other vehicles in an area by the responsible area commander. These markings may be authorised for any significant and essential reason and are valid only within the area under the jurisdiction of the responsible commander. They must be removed when no longer required for the priority mission; they may not be displayed when the vehicle is not actually on a priority mission.
    1. The priority sign will be made of sheet metal in the shape of an equilateral triangle with one point down. Each side will be 12 inches long; the corners will be rounded to a 1/2 inch radius. Refer to figure 9.
      Figure 9
      Figure 9: Priority sign
    2. The background colour will be lusterless white, Colour Chip No. 37875. A 1 inch wide border will be lusterless red, Colour Chip No. 31136. The military symbol of the organisation whose commander authorised the priority will be centred in the triangle. Colour of the symbol will be lusterless red, Colour Chip No. 31136.
    3. All symbols used will conform to FM 21-30.

11 - National Symbol.

  1. The national symbol is a 5-pointed star of lusterless white, Colour Chip No. 37875. It will be applied to all tactical and combat vehicles and appropriate equipment in CONUS and overseas. The symbol will be applied to vehicles and equipment only when withdrawn for issue to U.S. Army units. It will not be applied to ambulances or other medical service vehicles affected by international agreement concerning such vehicles.
  2. The marking will normally be applied to the front, rear, both sides, and top of the vehicle. The symbol may be applied to mounted equipment on vehicles when such equipment provides the most suitable surfaces. It will not normally be applied to canvas surfaces.
  3. The National Symbol marking will be located on the largest regular area and as near as possible to the centre of such area. It will not be applied in a location where it will, in normal usage, be obscured by paulins, canvas doors, folded-down windshields, gasoline cans, communications equipment, or other such items.
  4. Top surfaces for application of the National Symbol on transport vehicles will be in the following order of preference:
    1. Roof of vehicles with hard roof bodies.
    2. Top of cab on vehicles with hard roof cabs but not having hard roof bodies.
    3. Top of hood when no other suitable hard surface of adequate size is available.
  5. On horizontal surfaces the star will be applied with one point directly toward the front of the vehicle or equipment. On vertical surfaces the star will have one point directly up.
  6. The star will be applied in either of the two methods of permanent marking, stencilled-paint or pressure sensitive adhesive vinyl. Vinyl markings will not be used on highly irregular or rough surfaces where adhesion would not be complete. National Symbol markings at different locations on any one vehicle or piece of equipment may be applied in different methods.
  7. The National Symbol will be the largest size practical for use in the available space, but will not exceed 36 inches measured between opposite points. The star will not be applied in sizes less than 6 inches between opposite points.
  8. See table A, Appendix, for recommended sizes and locations.
