They can, and could change the vast majority of problems facing the CAF today; from procurement, to housing, to pay and allowances, to SLT and any number of things that piss us all off.
The issue: political will and desire to expend political capital on the CAF's betterment.
I don't count many governments in Canadian history, of any political stripe, that are willing to spend those votes on lil ol' CAF.
Policy is a great strawman that no one argues with.
