So a bank has an extraction team. Looks like a cyberpunk novel. I suppose extraction team come from a "security/mercenary" company. I'm curious of the legal implication.
If you're large enough it makes sense to be vertically-integrated with services you need frequently. They have a lot of wealthy people who need to operate in insecure regions, it makes sense that they'd deal with kidnappings etc. relatively frequently (indeed I'd look askance at an employer that expected me to work in a dangerous region and didn't have a policy/plan for such occasions).
There are any number of private security organizations; like any industry most (but not all) are professionals who know and operate within the relevant laws.
