If you integrated a Global Positioning System (GPS), a compass, a frequency tuned laser and a secured communications system, be it Radio Frequency (RF), cellular (GSM), or satellite, it would greatly enhance the suit. It would assist in the Command and Control (C2) tracking all suits within the Area of Operation (AO) and data transferred to each suit would allow the operators to have an Identify Friend or Foe (IFF) system which would be invaluable in a limited visibility environment. The GPS would provide additional information as to the suits exact location, to include elevation, speed, bearing, time to target. etc... (more fields located

The addition of a tuned laser would allow for range finding which would enhance targeting. When integrated, it takes the operators exact position from the GPS, the bearing of the laser from the compass and the distance provided by the laser and provides an exact location of the target. Depending upon the quality of the system, you could get range finding capabilities out to 10km/6 miles. In a SWAT environment, your sniper/observer (S/O) stalks in and takes position over-watching the target. He then designates his target with the laser which in turn transfers the data to the assault element approaching from a covered and concealed location. As they are in a covered and concealed location, they have no direct visual of the target, but yet a red icon pops up on their HUD giving them distance and direction to target 4. Off to the side of their HUD a projection of a small vid screen provides observation as seen by the S/O team. If you had a GPS Beacon tagged onto a target, that data could in-turn be broadcasted to the HUD.
The laser could be used for terminal guidance of munitions. In today's environment we see this predominately in the military sector. Although, with an increase in super-powers one may find the need of precision fired weapons which could remove targets capable of withstanding high levels of damage. How invulnerable is a PC/NPC to a Hellfire missile fired from a drone? He may be able to survive detonation, but the explosive force is going to "push" him, say off the top of a 100-story building.
An integrated laser could provide the operator with a laser microphone capturing frequency vibrations off of a hard surface. A S/O team moves into position outside of a structure and initiates his laser microphone targeting the window. Sound waves from inside the room are captured as they bounce off the window and transmitted back to the S/O team where they are broadcasted over the audio channel. As the PC/NPC's discuss their plan on how to elude the SWAT team moving in around them, they might have just called the SWAT C2 and told them the entire plan in person.
