From the pure standpoint of being an actual "presidential" protection unit, they're probably not that good.
I once talked to a retired Secret Service veteran, and he said most third world dictators had bodyguards that were more in the line of bully-boys than actual protection against the kind of assassination situations our President might face.
He said you could always tell their actual effectiveness at the real job, because they mostly went in for flashy para-military training and skills.
He said that being a hand-to-hand expert and being good with an assault rifle was nice, but when the real threat is a sniper, bomber, or just a nut in the crowd with a pistol, all the para-military stuff is a non-starter.
REAL bodyguards are very low-profile. The pros are the bland looking men in the background who never look at the man their guarding.
They're looking for the threat.
Another failing of these type of guard is, they're TOO close to their man.
Like Kim Ill's raised from childhood, Hitlers True Believers, and Saddam's childhood friend turned bodyguard, they're Hero worshipers.
As such, they're really watching their Hero, not for real threats.
The US Secret Service serve the President. They may actually HATE him, but it's the OFFICE they guard.
As such, they are able to stand back and keep their eye on the real purpose of they're job.
According to him, the tough-guy bully-boys usual contribution to the job involves shooting down everybody, innocent or guilty, in immediate range AFTER someone takes out the Man.
His best statement was, that these third world guards are like a cheap, nickel-plated pearl-handled Spanish made pistol: Flashy and looks good, but don't expect much when push comes to shove.
