been shifted away in order to declutter the display. It goes straight down from the symbol's centre left, then angles towards the actual location (see diagram). Feint/dummy (field AB) Identifies a unit intended to draw the enemy's attention away from the area of the main attack, or a decoy designed to fool enemy intelligence. It consists of a dashed chevron, placed above the frame, like the echelon graphic modifier (the standard is unclear as to how the two combine graphically). See Feints/Dummies, below. Installation (field AC) Identifies a particular symbol as an installation. It sits atop the frame. See Installations, below. Auxiliary equipment (field AG) Indicates the presence of a towed sonar array (used exclusively in the sea surface or subsurface battle dimensions). It sits below the frame, like field R (see Auxiliary equipment, below). Area of uncertainty (field AH) Indicates the area where an object is most likely to be, based on the object's last report and the reporting accuracy of the sensor that detected it. This can take various forms, such as an ellipse, a bounding box, or lines indicating probable bearing and distance. Dead reckoning trailer (field AI) Identifies where an object should be located at present, given its last reported course and speed. This can take the form of a dotted line (extending from the symbol to the dead-reckoned position) or a dotted circle (bounding the zone the object may have reached since, when the direction of movement is unknown or uncertain). Speed leader (field AJ) Depicts the speed and direction of movement of an object. It is identical to the Direction of Movement indicator except that its length is variable (and there is no arrow head). Pairing line (field AK) Connects two objects. Feints/dummies and installations Source: Mobility and auxiliary equipment Source: Text modifiers Quantity (field C) Identifies the number of equipment items present. Reinforced or reduced (field F) Displays (+) for reinforced, (-) for reduced, (±) for reinforced and reduced. Staff comments (field G) Additional information (field H) Evaluation rating (field J) A letter-and-number reliability and credibility rating, assigned by Intelligence. Combat effectiveness (field K) Signature equipment (field L) Used for hostile equipment; "!" indicates a detectable electronic signature. Higher formation (field M) Number or title of higher echelon command. field M of this company symbol shows that it belongs to the 42nd Armored Infantry Battalion: Hostile (enemy) (field N) "ENY" denotes hostile equipment.
