To be blatant this is just in the hopes that we ever see something like ACRE implemented into the game & maybe radio towers affecting radios.
Electronic Warfare what does that entail; For some it entails jamming enemy radio communications, listening in, generally mischievous activities that have to do with the oppositions tech.
ie. Your enemy is relying on their radios/some type of SCI-FI hud such as that in ghost recon, the ability to jam the usage/function of such could change how things are played.
Radars/Other early detection warning systems such as stations (Mike 26?) whose function is to alert the owners of such installations to any act of aggression/suspicious military activities. Jam/Destroy a radar, fly right into someones house & drop a bomb.
Some (Not all) Special Operations black hawks & the AWACS have the ability to jam/monitor communications, radar floors, things like that which everyone thinks are just Hollywood gimmicks.
So, by this point you've likely asked yourself who cares, why bother & what the hell is an AWACS.
AWACS on wikipedia: http://en.wikipedia.org/wiki/Airborne_early_warning_and_control
The reasons why it should be implemented, it adds a new variable which no game has yet delved into exploring thus far to its extent in a video game. Why shoot people when we're going to have automated turrets that you can hack & have THEM shoot people for you? Save bullets, proper usage of tax payers dollars. Everyone's happy.
Say maybe towers are implemented, you want to make a Special Operations Mission of some sort, so you want to cripple a larger forces ability to communicate by disabling their radio tower, whether by destroying it(Overt) or placing a jamming device in the control box(Covert). Either way you've just gone into a new area of Gameplay that hasn't been tapped to it's full potential, most importantly in MP.
Enemy has drones & a lot of guys, even the odds, hack their drones & make you're own BO2 mission.
Though to counter such capabilities & remove the "Tech is useless if it's going to just get hacked every mission" complaints there should be ways to counter it, via some type of mini game played at a laptop/controller area of some sort, or using your own jamming device, etc.
Why let big publishers have all the fun?
