That hardly explains so much $$$$ spent on ammo when they could just as easily bought office furniture with it. Ammo isn’t going to make their lives more cushy but a nicely decorated office with a big leather desk chair would. That also doesn’t explain why so many gov depts who have no need for such large amounts of ammo were ordering it too.
Different category of budget item, that money is a lot more limited and the government says you have to use GSA contracts for a lot of that stuff.
In some cases, the building/office with all the furniture is handled by GSA and we don’t have anything to do with it.
