I'd like to take up the point you made earlier, because i perform a good Arma JTAC<->CAS-Pilot situation with the lifelike CAS 9-Liner Card. But without Voice Chat it is terrible and take any longer before arrival. On the downside, anybody can pick up a Laser Designator and 'Call' for a CAS:
Soldier: Tank!!!1 Mark it with laser! Where is the CAS?
Pilot: Coming!! *drop, splash & done*
(effectively & quickly)
I know Arma is a game, and i know everone is here for the fun (a few for more )....
