Then I got info and pics from
www.militaryphotos.net and
www.google.com
Searching:
PMC (Private Military Contractor)
PSD (Private Security Detail)
Civilian Contractor
Security Contractor..... and so on.
The S.W.A.T. magazine, which I subcribe on, have had some great articles about the Civilian Contractor. From tactical training to "guns and gear of the civilian contractor", thats great stuff to read.
* If some one want, I can refer to numbers so you can order "backissues".
This is some of the material, theres a great deal of info out there.
Hope you like some of it any way!
