Nope. I am a Campaign Writer. I got a team to do my bidding and bring me stuff . Never done a airplane or such myself, but you will find getting permission is not very difficult. Do check the guys who are signed up for the CA Modders Agreement and thats quite many of us.
I never am. I just think a little more North then Netherlands ;-)
You must dig into a file called Nations.ini. Find it (or extract it), then add this:
[Nation (NEXT NUMBER IN LINE)]
Name=CIA
DisplayName=Central Intelligence Agency
Alignment=FRIENDLY
PilotNameList=NamesUSAF.lst
RankList=RanksUSAF.lst
CallsignList=CallsignsUS.lst
Formation.Fighter=USFighter
Formation.Attack=USFighter
Formation.Bomber=USBomber
Formation.Transport=USBomber
Formation.Tank=USTank
Formation.MobileAD=USAD
PilotTrainingStandard=EXCELLENT
GenderRatio=0
DebriefSuccessMusic=DebriefSuccess.wav
DebriefFailMusic=DebriefFail.wav
DebriefKilledMusic=DebriefKilled.wav
SpeechFile=USAFSpeech.cat
SpeechTextFile=USAFSpeechText.cat
Medals=MedalsUSAF.ini
MedalTextFile=MedalsUSAF.str
UseFAC=TRUE
ActiveDate=1948
AlternateDecal=USAF_OLD
Then you can add CIA as its own service the usual way.
That is tricky. However, like I said, an Air Offensive is your best bet, but I suspect that you already use it for the start. It also means alot of friendlies in the blast zone. Look for the "AirOffensive[001].Primary=WAREHOUSE" lines. Add a AirOffensive[001].FocusArea=Hanoi
Lastly, add StartOffensiveDate=03/05/1966 (Change the date for the day your new squadron appears).
