FBI's HRT is NOT on the same tactical and proficiency level as Delta Force...
And to be a core collector/case officer (non James Bond type Spy), you do not need military experience, you need good academic experience, foreign languge (not spanish) knowledge, and overseas travel and experience.
To be a paramilitary operations officer (covert and clandestine war-zone operative), you need special operations military experience (as of the post 9/11 world, in the pre 9/11 world; legs and cops could become PMOs). To be in HRT these days you need special ops experience, so going from HRT to CIA means you already have special ops experience... get it? **
**theres a small percentage of HRT members who rose up to the ranks from the Special Agents positions and not under the Tactical Recruiting Program**
But back to your original question... a member of HRT with no special operations experience could 100% be recruited to be a Paramilitary Operations Officer, as well as a case officer. He is still considered a special operations tactical operator since counter terrorism and hostage rescue is a piece of the special operations spectrum. (Do not relate SWAT officers to be even close to the same level as HRT). And plenty of HRT boys go to Iraq and Afghanistan, I know this because we have raided houses in Iraq side by side with HRT guys (individuals, not whole teams).
