Canada as a caution against fully unified armed services

Would combining every military branch into one unified service stop interservice problems?

The objection is Canada's experience, described here as a difficult effort to separate previously unified forces; Australia is suggested less certainly as a similar case.

A proposal to combine all the armed services assumes that a unified institution would remove interservice problems. Dr. Clarke objects using Canada, describing its previously unified forces as undergoing a difficult process of separation. He tentatively suggests that Australia is moving in a similar direction. The Canadian example is his reason for doubting that complete institutional unification provides a straightforward solution.
