* A combat support and
combat service support element.
In the logistics concepts and doctrine phase, we examined the theory, nature and levels of logistics and the Marine Corps warfighting philosophy as set forth in MCDP 4 followed by a comprehensive examination of principles/functions from the perspective of MAGTF/ACE/GCE G4/S4 and
Combat Service Support Element (CSSE) G3/ S3.
In addition to the ACE, a command element, ground combat element (GCE) and
combat service support element (CSSE) comprise the MEU, which embarks three ships of a Navy amphibious ready group (ARG) under the command of an amphibious squadron.
A MAGTF includes a command element, a ground combat element, an aviation combat element, and a
combat service support element (CSSE).
Additionally, CBRN companies will be aligned with maneuver and
combat service support elements for brigade combat teams.
