Squad diserter implementation

I have seen a few posts about the lack of gameplay with randoms in squads.

With such large maps, I wonder how simple/hard it would be to incorporate a distance-based alert that gives the squad leader an option to mark another squad player as a deserter.

This could give the player a warning and then subsequent quality of life actions that are annoying, like red screen filter that makes it hard to see or a constant voice or notification message directing them back to target.

I haven't thought this through at all. This is just straight off the top of my head.

Maybe someone else can elaborate or put this better into perspective.
