Official abbreviations.

Well, it might be usefull to start a list with the official abbreviations of each air arm. Maybe someone who’s got some spare time to fill in.
The reason why I started this topic is because in a lot of magazines the wrong abbreviations are used (like RKPAF for the DPRKAF and PRCAF for the PLAAF, as seen in the March issue of Air International). Also, there are some minor differences between the RSAF (Republic of Singapore Air Force) and the RoSAF (Royal Saudi Air Force).
