The radio operator could carry an M16, a couple of frags and some sort of communication radio on his back.
Here's what he would do:
- If you switch to the radio "weapon" in your kit, the guy would reach behind his back and grab the radio phone piece.
- The crosshair would be a large circle (about half the size of the screen).
- When you hold down the fire button, you start transmitting the location of enemies within your view.
- When you are transmitting, the enemies show up on all friendly maps (much like a UAV does, except they are persistent--not like a radar that goes around in circles).
- Maybe you should have a meter (like medic, engineer), or maybe not, I don't know.
The idea is that you have a radio operator who will relay enemy locations from a distance. While he is doing this, he cannot fire or move. (is it possible to make him need to crouch/prone in order to transmit?).
He will be distinguished by the radio pack on his back (no, not those huge WW2/Vietnam packs) -- so enemy know who to shoot first

As far as the enemy forces?
Well, quite frankly I dont know who the Marines will be fighting
They should use other means by which to communicate enemy locations amongst one another.
