This chapter establishes a standard system for the development of ground unit symbols. These symbols are for use on situation maps, overlays, and annotated aerial photographs. This chapter applies to both automated and hand-drawn graphic displays or overlays. This chapter includes a wide variety of unit symbols as well as modifiers for building new or unique symbols.
Users should avoid using any symbols, or combinations and modifications of symbols, that differ from those in this manual.
If the user, after searching doctrinal symbols and modifers, must create a new symbol, it must be explained in an accompanying legend. The symbols 101-51 in this chapter are adequate for depicting enemy units.
When representing unorthodox units and equipment,select the most appropriate symbol contained herein. A symbol is composed of three components: Frames are geometric shapes used to display affiliation.
FM , Operational Terms and Graphics, Table of Contents and Preface
Affiliation refers to whether the warfighting object being represented is a threat. The basic affiliation categories are friendly, unknown, neutral, and enemy. The unknown frame shape is normally used only for aircraft and ships. The frame shape for suspected friendly, enemy, or neutral is used for ground units not positively identified. The basic frame shapes for units, installations, activities, and logistics sites are shown in Figure Fill refers to the area within the frame.
If color is used in a symbol, it shall indicate affiliation.
Generally, black is used for the frame, icon, and modifiers when symbols are displayed on a light background. White is used for these elements when they are displayed on a dark background. A color fill can be used if an icon is displayed within the area of the frame.
The use of any other colors must be explained in an accompanying legend. Automated systems allow mf to select other colors and to portray their meaning on the automated overlay display. The icon is a “role indicator” that shows the warfighting function the unit performs either on the ground, in the air, or at sea.
An example is the crossed rifles which represent an infantry unit. This manual does not include an example of every type of unit; however, users can see from those presented the pattern of construction in order to make symbols f, new or unique units.
Appendix A includes additional examples of friendly units. Appendix B includes examples of enemy units. Agmy, additional information needs to be included with the unit symbol and is placed in standardized unit labeling fields shown in Figure The fields are defined in Figure The unit location is determined by the center of mass of the symbol or a line without an arrowhead from the center of the bottom of the frame to the location.
Headquarters unit locations are at the bottom of the “headquarters staff,” displayed as field “S. As an example, we will build the symbol for a friendly nuclear, biological, or chemical NBC reconnaissance unit equipped with the FOX and M21 long-range sensor.
Figure shows the abbreviations used when identifying units or marking boundaries. Situation maps and overlays provide a rapid and easily understood means by which 1101-5-1 commander or staff may express an operational plan, concept, or friendly or enemy situation.
The combination of unit and fn symbols with objectives, boundaries, routes of march, and other control measures creates an indispensable tool for quickly and accurately portraying battle activity. Standardization of techniques is essential if tactical information is to be relayed without misunderstanding. Present and Proposed Locations Basic unit and installation symbols are drawn with either solid or broken lines.
The center of mass of the symbol indicates the general vicinity of the center of mass xrmy the unit. If a staff is added to identify a headquarters, the base of the staff indicates the precise location of the headquarters. Precise Locations To indicate locations more precisely, the following methods are employed.
Sign In Sign Out. Frame, fill, and icon showing basic function of units, installations, or equipment with modifers A1,A2, and A3. A symbol that denotes the size of a unit or installation see Figure Indicates number of items present. Size in 101-5–1 feet. A symbol placed over the size indicator to denote a task force 101-5–1 company team see Figure Number or title of higher echelon command corps designated by Roman numerals.
Direction symbol is moving or will move. I dentifies unit symbol as a headquarters or used to indicate location or to declutter. An alphanumeric title that uniquely identifies a particular symbol; track number.
Friendly delivery unit missile, satellite, aircraft, etc. Altitude portion of GPS. Flight level for aircraft. Depth for submerged objects. Height in feet of equipment or structure on the ground. First choose the frame friendly and graphic for the basic function or branch of the unit, labeling field “A,” In this example, the basic function is NBC.
FM , Operational Terms and Graphics, Chapter 4, Unit Symbols, (Continued)
Choose the graphic modifier for the secondary function or capability, labeling field “A 1, ” possibly from the list of modifiers. In this example, the secondary function and first modifier is reconnaissance.
Choose the graphic modifier for the next capability, labeling field “A 2. Choose the graphic modifier for any other capability, labeling field “A 3. This example requires no more graphic modifiers.
If necessary to fully distinguish the unit from another type of unit, include a text abbreviation, labeling field “A TEXT, arrmy inside the symbol frame. In this example, a text abbreviation “RS” is added inside the symbol to show that this unit is specially equipped with the M21 sensor. Unit size indicators, shown in Figureare placed at the top center of the symbol frame in field “B.
Basic symbols other than the headquarters symbol for example, points may be placed on a staff which is extended or bent. The end of the staff indicates the precise location.
FM 101-5-1 Operational Terms and Graphics
Since the headquarters symbol already includes a staff, this staff may be extended or bent. The end of the staff, or extension if usedindicates the exact location of the headquarters. If several headquarters are at one location, more than one headquarters symbol can be on a single staff. If a group of units or installations other than a headquarters is at one location, the grouping of symbols may be enclosed with a bracket and the exact location indicated with a staff.
