Do you have a link that shows that breakdown?
No mink for it.
he way you can do it, is this :
* start with the US Federal Budget ( like here
https://en.wikipedia.org/wiki/2010_United_States_federal_budgett ).
You have mandatory spending, and discretionary spending.
For each you have the departments.
Go through each department spendings ( look the way it is divided), then ask the question , should this be in military or not? then has it already been counted in military? if not add to militaruy, and you have you new non-military(whatever department) budget.
You also need to look to the divisions in tax collection ( businesses who pay little taxes, get subsideies, tax reliefs, etc) . As well as individuals ( veterans in military or civil)?
I hope you have friends that are interested to find out these.
The military spending and subsidies are very hidden for the US.
What you can do, is trace the companies that the money goes to and more often than not hand into the hands of republicans more often than democrats. For unknown reasons democrats are more into "hippies" and "peace and love" type of business .
You will also need to check the evolution of these budgets directed via tax or payments or subsidies to the military : they normally will not change, but in total increase. Very hard for presidents to change that ( very strong military-industry special interests).
