This is a good precaution in an era of great power competition:
The Army National Guard will move most of its brigades under the command of its eight division headquarters as it reorganizes its fighting formations to give the force more combat power and some soldiers new career opportunities, officials said.
I wrote in Army magazine about putting our Guard divisions into our war plans back when only enhanced separate brigades were even remotely considered.
To be fair, the whole war on terror thing interrupted my prescience.
