CIA Vietnam war controlled USAF aircraft missions

I have on good source from a knowledgeable aviation enthusiast, info
that in the late stages of the Vietnam war for some operations the CIA
controlled a limited amount of USAF assets, eg F-4 Phantoms and F-111s
Adavarks for attacks in Laos and Cambodia.

These aircrafts were painted overall black for night operations and
operated by only a pilot, no wso, due to CIA mission rules.

They were operated in Strike and Recon roles as i have been told. This
leading to a possible use of RF-4Cs i was told.
Time spent on the subject wasnt long so i wasnt able to get a confirm or
denial from the person.

The aircraft would depart their bases early in morning/late evenings and
no radio chatter was observed.

If they were shot down they were not given any chances to be rescued due
to the nature of their mission.

Anyone else ever heard of this operation before?

The person told me, not many people knew it even existed at the base the
planes flew from.... he didnt know which base/s the planes flew from...

What i was told... sounds like a unknown low key CIA/USAF secret
operation only known by a few people? eg never made public yet since the
war .. or could it be a fake story?

Since i dont know what the CIA would want from USAF aircraft in these
roles... it does make me wonder..

What was so sensitive in Laos and Cambodia that would require them there
?
