Ok so he got the incorrect jurisdiction but his question is valid..and I reckon they must have a plan in place.
I would imagine. From what I heard they have all kind of plans just in case, no matter how absurd. I am guessing there's a degree of completeness to a plan ie is it just on paper for a hypothetical scenario or some units assigned with training carried out.
Pretty sure they’d be embedded with SAS/SEAL or delta
I was guessing it would not be an assassination by a squad but rather a covert mission such as poison and such.
This is all just guessing, I lack even basic knowledge about military things.
