So I’m not sure what this factoid is proving about bright futures.
US Army Corps of Engineers for example maintains levees and dams throughout the USA. https://en.wikipedia.org/wiki/United_States_Army_Corps_of_En...
Yeah, that's part of the DoD budget. Really weird, but that's how we budget for things in the USA.
Then there are mixed-projects, like Military colleges and schools. Officers are all college-educated, so when they leave the military, they still benefit private industry all the same. Or DARPA's contributions to the advancements of science (Adoption of TCP/IP and other long-term research projects)
$4.8 billion / $639.1 billion = 0.75%
It's a minuscule part of the DoD budget. A rounding error.
The majority is spent by the army, navy, and air force. The biggest expenditure category is operation and maintenance, followed by personnel, then procurement.
Who do you think has a brighter future?
