Yes for the most part they do. But each countries military have places that these things made for them are tested and here is where the problem of the money comes in. Approve our Plane, Tank, weapon and we will slip you some Cash, stock, perk. First the contracts are looked over and then a company or two are awarded the contract. Mabie they are looked over and Mabie not. I haven't had any contacts in that area for over 40 years. Then a prototype or two are made and tested. For Tanks and cannons it is at Aberdine Proving ground for missiles it is at Vandenberg space flight center. Hey Give this one a good review and we will compensate you. How else do the Government employees make enough money to have three houses some in other countries and a fat bank balance in several different Banks. Oh I am a simple Full bird col. that makes 200k a year but have three houses worth over 100 mil. Or the congress man that makes 15ok a year but is worth 500mil. And its not just in the U.S,A. that this is going on.
