In my mission, the guys in your "squad" aren't actually in your OFP group. Since you are the only one in your group, you do not have any of those radio commands, or the "birds eye view". One of the main reasons I did things like that was to get rid of that damn view, which is SO cheap.
Those radio controls are hard-coded into OFP, and there is no way to touch them via scripting, AFAIK. Only way is to "fake it", and have the player by himself, controlling his "squad" via other means.
-------------------
HOWEVER, there MIGHT be an exception, if you are making a mod. I have heard that there is a way, via the config, to replace some of the default radio controls. Only problem is you can only replace them with the normal alpha-bravo-charlie trigger controls. Anyway, I don't know much about this, but I might be able to dig up some links/people if this would work for you.
