Personnel Inefficencies...

I hope that JFCOM goes by-by because it's an empty suit that has no purpose.  The money and personnel used to keep it going can be and should be used elsewhere.  Or it should be sacrificed so cuts DON'T have to come from where they can be least afforded. 

Another way to cut personnel, included the ones you have to deploy, would be to rework the way the Army and Marines do administration.  Instead of individual units have admit shops you combine all on a per-duty station basis.  Assign on Admin Clerk per company under the 1stSgt as a go-between and have all the work done by more efficient centralized Admin shops who can do what they do in large FOBs in Iraq and Afghanistan just as well as they could w/o leaving CONUS.  Likewise totally eliminate the position of G-1/S-1.  They are no longer needed.

I would cut the Artillery Regimental HQ and Assault Amphibian Battalion (including 1CAB) out of the Marine Corps.  They are not tactical or operational commands.  They are purely administrative but they have all the trappings of tactical/operational commands.  I would still have a Regimental Commanding Officer, but his job would be to ensure that the regiment's battalions have the training they need, the equipment they need, that the equipment is in a good state of maintenance and to help the Division HQ to both plan operations and co-ordinate operations.  For this the Artillery Regimental 'Commander' would need an operations officer to help the planning and co-ordination, a Regimental Training officer and  Regimental Maintenance Warrant Officer.  Any 'regimental assets' that are truly needed can be pushes down to the battalions.  The Regimental CO would retain the authority needed to insure the battalions under his command are war-ready, the regimental CO doesn't need a bloated staff to do it.  Likewise the AAV Battalion HQ could likewise be reduced and the battalion commanders would be to each division the same as the artillery regiment's commander.  I would also go looking for units that likewise could go through this transformation.  You would be surprised the personnel you could save by doing this. 

I would also do completely away with one marine unit in particular.  CommCo, H&S Battalion, 3rd FSSG.  The FSSG already has a WHOLE Comm Battalion under its command (in this case 7th Comm Bn) that could provide all the communications support the FSSG HQ needs, there is no need for a separate Comm company.
