Mr Rawles,
Thanks for hard work and invaluable resources. I have a suggestion buying surplus military equipment. It appears the government liquidators mentioned have some sort of fees involved. Anyone can go to the DoD’s Defense Reutilization and Marketing Service web site. This eliminates any middleman and lets you look at available equipment online.
In addition and maybe more usefully, every military base that I have served on or visited had a Defense Reutilization and Marketing Office (DRMO), and they hold regular sales, some walk-in like a surplus store and others by sealed or open lot bidding. – J.J.
