Well I think comms was on v3, near the crashed blackhawk by fac, so that could be one, another one could maybe be the graveyard by old RU base, perhaps that's a stretch because it's literally just outside their base. Maybe both faction outposts. Honestly I'm not sure if there are sufficient tiny locations on v3 to support this type of gameplay, although I do like the concept, I don't know if its do-able, would definitely have to see the map again.
