Wavell Room – What can you do with amphibious forces given current area denial, especially sea denial, measures; particularly in Europe?  Those tools of sea denial mean that fouling the waters is easy but clearing them is hard.  Because of this, sea denial is easier today and sea control is growing more challenging.  Threats to large landing ships make traditional amphibious assaults—called forcible entry operations in the American vernacular—riskier.  Simply using amphibious forces to do ground operations in a new patch of land is too hazardous.  On the other hand, a divergent model has promise to contribute to sea control.
