What be this NECC? Also from what I have read, this current incarnation of the US Marines started in 1933. That is when they decided to create the Fleet Marine Force. Basically another land army. Before then, regular Navy Sailors took part in amphibious assaults on foot. I made a thread about this https://www.history.navy.mil/resear...abetically/s/sailors-as-infantry-us-navy.html As recently as USA second invasion of Mexico while Europe was fighting WW1, US navy sailors took part in the second capture of the port City of Veracruz. They also had a large role on the ground during the Banana Wars.
