Enemy Infantry

Enemy Infantry - commonly called "EI" - is a general term that describes exactly what it says: one or more Infantrymen that have been positively identified as belonging to a Side that is hostile to the player using it. The term may refer to either player-controlled or AI-controlled enemies.

"EI" can be called out on the Radio or by Voice, together with enemy's general direction and distance, alerting anyone listening to the presence of those enemies. If the strength of the EI force can be estimated with any degree of accuracy, the call may be followed by the word "Fireteam", "Squad" or "Platoon" as appropriate; otherwise this is not noted. Finally, if the EI are moving in a specific direction, that direction can be noted as well - using either cardinal directions (e.g. "moving east to west") or relative directions (e.g. "moving left to right").

Similarly, Map Markers are typically placed down to denote the EI's location, especially when the group is large or when trying to call the attention of another unit to enemies that might threaten them shortly. EI Map Markers are also used to target an EI unit for Close Air Support or Artillery attacks.
