The sums are vast, but the explanations for the spending range from vague to inscrutable. Consider these items in the law that funded the Department of Defense this year:
For “Other Procurement, Air Force”: $32.6 billion. For “Research, Development, Test and Evaluation, Defense-Wide”: $35.2 billion. And for “supplies and associated support services” related to U.S. Code Title 10 Section 3601 subsection(c)(3)(B) clauses (i) through (iv): a mere $650 million.
