Is IAM a new callsign used by the Italian AF?
Never heard it before, seen it appear on Mode S logs the last couple of days and today the first time I heard it (on Athens ATC):
IAM4669 (C-130J MM62190 46 BA) pronounced as "Italian Air Force" by pilot
IAM3112 (A319 MM62209 31 St) pronounced as India Alpha Mike
First two digits seem related to the Wing?
