"Globally, the use of PMFs has grown dramatically since the 1990–91 Gulf War, when there was an estimated one contractor for every 50 military personnel involved. By the time of the Iraq invasion in 2003, the ratio had grown to one in 10. With PMFs operating on nearly every continent and generating an estimated $100 billion in revenue annually, they are certain to remain important actors in military affairs for the foreseeable future."

This shows that the military appreciate the usefulness of  private military contractors and don't disapprove of them.  This also shows that being a PMC is a good way to make big money.
