SAS and SBS both work in teams but are never true Black Ops. You're talking about Special Forces, which is exactly what Havoc Squad is. They're the ones called in when a nation wants something done.
What [member="Kyla Verss"] is creating is a squad of people that do things a nation wants done but doesn't want anyone to know about. While the CIA do serve the function you speak of, they also have carried out things like i described(There's several memoirs of CIA members who describe being a part of operations like Kyla described). Intelligence gathering is only a small part of what Intelligence Agencies actually do
Besides those facts, it was more of a comparison anyway. Havoc is out in the Open, Kyla's Squad is not, they work in the shadows doing the dirty deeds.
