Actually, military equipment SHOULD be getting cheaper, and so should armies.

The IT and solid state electronics evolution and all it's spin-offs should have created considerable savings, and actually has, in terms of procurement and ownership. Civilian cell phones are far more complex than a lot of military radios, yet cost nothing.

If you want to see true corruption, look at the companies that build Sniper Rifles!! Gold Plated Wheel Chairs!! UAVs cost vastly more than they should, and the list is almost endless.

The problem is how the equipment is procured and how the money is spent.

One day this will all bite us in the ass as folks like Hezbollah and Venezuela can go out and just pay for military capability, and not worry about the budget shell games of the DoD and MoD.
