It all really depends on what you do with your career, what agency you are in, etc.
For example, I have taught a lot of swat/firearms schools, done 9 years on a federal agency's national tactical team (to include tours overseas), etc. This could open doors in training/instruction, as well as some security companies (more along the lines of assessment and management).
I have also done some financial investigations. A buddy who has also done this financial stuff has been talked to by banks for a retirement gig. They have mentioned 6 figures PLUS a commission on the money he would save the banks.
Others who like judicial security/witness protection could go into private security firms (well above the rank of bullet-cushion), do corporate security assessments, VIP security assessments, etc.
There are a ton of opportunities out there for "go-getters". Then again, on a federal retirement with generous contributions to your TSP (our version of a 401K) throughout your career, you probably won't have to work when you retire if you don't want to.
