A-02 / Legal boundary
Move appropriations merely by coordination
Transfers between appropriation accounts require legal authorization; the ordinary defense transfer framework imposes higher-priority/unforeseen-requirement and congressional-denial restrictions.
Scope and exceptions
A specific transfer statute or appropriation may provide different terms. Reprogramming within an account and transfers across accounts are not interchangeable.
Planning implication
A coordinating body can find legal routes but cannot make every DoD dollar fungible.
