Excluding some isolated incidents, I had never once touched Voice Chat until City 24 proper because I always hated feeling left out, like some others in the CP feel right now. I saw what some of these Rank Leaders would do and strived to not be like them. To be as inclusive as possible, to make sure people who I'm leading know what we're doing and what their role is.
And I did it all ICly. By talking to them. Because being in an area with a LOT of people yet hardly anyone is talking because they're all sat in a VC is demoralising and isolates people.
As you're able to tell through various videos posted, people in these leadership positions, primarily the Rank Leaders typically sit in their own calls together which isn't inherently bad, but interaction ICly still needs to happen a lot more than it does.
Even if an order has been issued at some point before, if a ground unit asks for a refresher over the radio "There's and unarmed person approaching the Villa, what's our orders?" a simple "Turn them away" or a "Shoot at them" order would have sufficed.
