Callout
A clear, short spoken report of what you see.
A callout is a short, clear spoken report, an enemy spotted, a direction, a rotation, so the Squad acts on the same picture. Callouts are what make Flanking, combined arms and holding the Control Zone actually work, and they run over voice comms like AE COMMS. The team that talks wins.

AE Gaming runs organised WARDOGS every night with free comms, a planning map and a base builder. Reading is half of it, the other half is a squad.
