Seer Combat Information System
Tactical information sharing network used by the Grand Army. All vehicles, battlesuits and aircraft in an area linked into the Seer CIS; the leader of each infantry squad has a forearm unit linking Grenadiers to the unit. The Seer CIS integrates all available sensor info into an integrated map of the battlefield, that any GA soldier can access. Officers use can also use this network to coordinate attacks, call for fire support, and request reinforcements.
The Seer CIS allows the GA in battle to act seemlessly and organically, allowing them to 'march separately and strike together'.
