I regard any world-class bad guys as being able to hire top-end former miltary guys: ex-SEALs, Marines, KGB Alpha Teamers, SAS, etc, as well as regular soldiery. His bodyguards would certainly be supersoldier types. And they would definitely all have KS: Superhuman World on an INT roll, as would his regular agent types, the guys who did the gumshoe work for him. And they wouldn't be mooks either, but smart, tough, capable professionals, on the level of undercover police or MI5 types.
The idea is that the PCs have to work at defeating these guys, they can't simply one shot them. Or not more than once, anyway.
