PMC's Before T2k

[kalos72]

So my campaign regularly has contact with a PMC that is loosely based on MP, having both a Security and a Science Division.

I have this corporation taking over the security on several Airfields, Power plants and other assorted government facilities.

Any thoughts from the experts on what the PMC world looked like back in 1995 forward in a T2K world? Real life examples or pure T2K...
