Electronic warfare is definitively in the plan.
However, as exsonic01 correctly pointed out, at the moment we are prioritizing more urgent issues such as the campaign generator, other basic game improvements such as larger stacking limit and improved pathfinding and of course fresh content in form of new factions.
I personally have to admit of being blissfully ignorant in delicate intricacies of modern ground EW, and remediating to something like that would require several months (if..) of reading, researching et hopefully understanding complex engineering aspects, so we absolutely encourage players proposing solutions. Particularly if backed by sources, or even better, personal serving insight. It makes things easier for us, and more likely it will get into the game sooner.
FM 3-12, from page 1-25, brief description of EWs.
FM 3-36, US army EW FM.
FM 100-6, Information operations, 1996
FM 34-1, I & EW operations, 1994
FM 34-80, brigade and battalion I & EW operations, 1986
1987 version of FM 34-1
Maybe you could be able to get a fundamental concepts and idea of US army EW during cold war from those documents. Brigade / Battalion FM looks good. But I'm not sure about PACT or any other NATO nations....
2017 ~ 2025 Russian EW expectation
Does the US army FM 100-1 and 100-2 (Soviet army study) contains EW of PACT or USSR?
All the manual and doctrine don't help as even the most basic performance data are still classified, unlike weapon system where you can actually have access to some un-classified performance data. So you basically just throw a number in the air and say this system will cause this effect purely in random.
