one Marine Expeditionary Force (MEF) plus two Army mechanized infantry 
divisions (MECH + HVY CS). This prepositioning function of the MOBS has 
been viewed as an essential component of the U.S. Rapid Deployment Force 
implemented in 1986. 
Three basic modules of a Deployable Waterfront (DWF) are preposi- 
tioned alongside the MOBS for 6-knot transfer by ocean-going tug to a 
designated shoreline site. The DWF is designed to operate functionally 
in concert with the MOBS as an integrated logistic port system to support 
combat forces ashore. 
MOBS is capable of incorporating any or all of the essential basing 
functions attributable to a major node in the U.S. forward basing net- 
work. Combat forces prepositioned on board the MOBS can be in a_ state 
of readiness including a Marine Expeditionary Brigade (MEB) with a com- 
plement of 15,000 combat troops. Either alongside or in the proximity of 
the MOBS is a Marine Expeditionary Unit (MEU) consisting of 2,000 amphi- 
bious assault troops afloat on Maritime Prepositioning Ships (MPS) with 
amphibious landing craft, equipment and supplies for 15 days of sustain- 
ed initial assault.
