Yup, especially since Mercs. are a common use in Military opperations world wide.
The USA has Black Water (or XI as they are now known), the United Kingdoms have the Gurkhas, The French have the FFL (who are also the French's Special forces), so on and so forth. Mercenaries are a major factor in war. However, the use you are refering too is about Merc.s (such as Black Water) who work as security for diplomats and CIA agents in the field, not as active military combatants.

There is no Immoral aspec to the USA's use of Mercs. What certain Merc. groups do is a fault of the Merc.s alone, not the employer in many cases, such as when Black Water went on a shooting spree when a squad over reacted to a situation, resulting in a unneeded masacre and the merc.s being ousted from the faction and shipped back home. However, Merc.s are also cannot, in most situations, be held accountable for certain actions that would be concidered war-crimes by any other army because Merc.s have no flag.
