purpose and functions of voice chat :/

[[ZOV] Pesh]

I am interested in voice chat, there is a local chat and squad chat.
it's more or less clear with the squad chat, but I didn't understand who can hear the local chat? will people around me hear it, or will there be a connection with all the people in the team?

PS: I apologize for the mistakes in the text, because I don't know English well. I also apologize if I wrote the wrong discussion, this is the first time I'm sitting on a gaming forum :)


Sincerely, Pesh from Novosibirsk :)
