Radio Communication.

When I first started playing Forefront i was ABSOLUTELY overwhelmed with the voice chat. The entire team was basically speaking at the same time and it goes straight into my ears. Making communication hard to understand whilst maybe 4-5 people outside of your squad are speaking at the same time.
I believe this can be remedies with Proximity chat with everyone in the game enemies and friendlies. As well as a radio system that lets you communicate with either your squad or nearby teammates upto a certain radius.
The radio function would operate similarly to how Pavlov handles its global communications/team broadcasting.
