CAC card number for Precheck?

Has anyone out there successfully substituted their CAC card number for their personal (paid for from personal funds) Precheck/global entry number?

I tried doing so on one airline in the hopes of a FA seeing it, thinking I was military, and comping me drink. Yes low grade stolen valor as I am a DoD contractor who has never served in uniform.

But instead my CAC number is not recommended at all and I have to stand in line with the poors. No bueno but probably just punishment for my attempt at stolen valor.

What are the experiences of others using their CAC number?

Contractors can’t use their CAC number for TSApre. It’s only military or DoD Civilians
