You may be thinking of how Congress funds the wars in Iraq and Afghanistan. They do indeed fall outside of the ‘planned’ DoD budget, even though we’ve been at war for 17+ years. They’re funded by special appropriations bills. This 16% ($605 billion) number includes $74 billion in a special Overseas Contingency Operations bill for Afghanistan. Alternatively, you may also be thinking of the DoD ‘black budget’, which is classified. That is included in the budget, but it’s not itemized or described in any way to keep what it’s spent on a secret. It’s typically around $65 billion.
