Total 2010 budget: $3.55 trillion dollars
2010 DOD budget: $663.7 billion

That puts the DoD budget at 18.7% of the overall national budget.

Of course, it also doesn't count things like the nuclear missile fleet (funded out of the DoE budget), Veterans Affairs, military research funded via the NASA budget and the NSF, etc. In total, it's probably about 25% of the overall national budget.
