Being able to communicate with other players (and enemies) through proximity chat is really awesome. Last night, while I was with my squad, we came across another squad of French-speaking players. We coordinated our efforts as best we could, but the squad chat is limited to four people. An interesting feature would be to have a walkie-talkie on the left hip that allows squads to communicate with other squads on their team. Of course, it should be possible to make a channel private if you want to stay with just your own squad, but this would create an even stronger sense of cohesion and camaraderie in the game. It would be fun to have some kind of dial to switch between different squads (Foxtrot, Charlie, etc.), similar to how the recon beacon works. Maybe communication wouldn’t be automatically active (like it is within your own squad), but only when holding the walkie-talkie and pressing the button — just long enough to coordinate actions. Perhaps it could even include a classic “walkie-talkie” sound effect to distinguish the voices of your squad members from those communicating through the device.
