Quoted:
Just had to educate my friend on this important distinction.
Security contractors have loyalty to their side, while mercenaries are only loyal to the highest bidder.
Blackwater isn't going to start working for the taliban if they suddenly come up with a huge amount of money.
Mercenaries would.
No... That's not the difference....
Mercenaries are active combatants - soldiers for hire...
Blackwater = Super-duper, elite special-forces Mall Ninjas....
Think Wackenhut/Securitas with automatic weapons & decent combat training....
Mercenaries can participate in offensive combat operations....
Security Contractors can only protect their contracted principals.....
(Kind of like how the mall ninja can't go chase down drug dealers & do traffic stops.... But private police (sworn LEOs working on contract) can)
