Since you can build a script into an addon, could it be possible to put an airstrike or arty script into the radio for the deltas and rangers? So that if you're near the radio man you have the action to call in a strike
(I noticed that in the airstrike/napalm airstrike (not sure on the maker) if you put the script thing in the init field of a npc and go near him you can use the script, so it could work.....maybe.....)
