This webpage only addresses apportionment of incarcerated veterans' benefits, which is the VA's process of taking all or some of a veteran's benefits that would otherwise be reduced or suspended due to incarceration and instead paying those benefits to the veteran's eligible dependents based on their demonstrated financial need.
Generally, veterans cannot receive monthly monetary Military Disability Benefits from both the VA and the DoD. Instead, any money a veteran receives for VA Disability is subtracted from the money he gets for DoD Disability or DoD retirement (basically from ANY money he receives from the DoD).
