Again, completely false:
GlobalSecurity.org is NOT a private security/military company, defense contractor, or vendor. We are NOT affiliated with any such entity and we do NOT sell anything. We also do NOT buy any military equipment, machine parts, or other such items. Our website has pages describing weapon systems and other equipment but we do NOT buy or sell them.
