''Homecoming'' Use to be a special type of operation back in the days, where the whole Cnto forces are deep inside enemy lines, all separated in small squads.
End goal is to manage to get back to our side and regroup along the way if possible.
Because you are in such small groups, everyone as to step up (Often it's in urban area) it's always really tense and butt tight kind of operation.
It gave me the best moment in my cnto history, when we started a recovery with Clarke in a little bird of a recovery mission previously lead by Ryujin which ''Perfectly landed'' (With a 90° somewhat angle) his Black hawk. Most Fun I ever had.
You are right. And buildings distort the radio's so I doubt you will hear people even 1 block away clearly. And maybe people have random frequencies in there radio so you have to figure out where other people are first ! Who knows ! Not me ! Or do I know ? I don't know.....
