The US Military ranks last in the world on the metric of equipment purchased per dollar spent:

In a study due out March 15, consulting firm McKinsey & Co. examined how efficiently 33 nations that account for 90 percent of worldwide defense expenditures perform a range of functions.

“The United States and Australia are the lowest performing countries with regard to equipment output for every dollar spent,” McKinsey concludes.

Brazil had the greatest efficiency of the countries surveyed.

The Soviet Union spent themselves to destruction on huge amounts of military hardware, and it appears that the good old USA is spending itself to destruction on tiny amounts of military hardware.
