We are looking for detailed information on the M1A2, preferably SEP update, to include:

Inter-Vehicle Information System (IVIS.) The IVIS system allows for the automatic and continual exchange of information between vehicles. By incorporating information provided by an on board Position/Navigation (POSNAV) system, unit commander's can track the location and progress of subordinate elements automatically, without tasking vehicle crews. In addition enemy positions can be identified, plotted and disseminated, while reports and artillery requests can be automatically formatted, transmitted, and processed. Lastly, map graphic control measures and operational orders can be rapidly distributed via the IVIS system.



Edit
There's a lot of innuendo about them improving CA on the DCS forums.
I even seen a post about a possible Tunguska module.
DCS are good a what they do, (Air warfare) but they have a long way to go if they want
To match SB, Personally If I was in charge of DCS I would scrap CA altogether.
Start again or contact Esim.
