The US military studied Vietnam a lot:
No more draft, career soldiers only Control the media One year tour of duty (they broke this one in Iraq because they were running low)

This is a big one I think. From what I've read, in Vietnam, you just needed to get letter from your local newspaper accrediting you as a journalist, and you basically got a free ticket anywhere in Vietnam with the US military.
Now it's a lot harder to get embedded as a journalist with military units.
