Interesting article about US Navy Sailors fighting on land like regular infantry, and I am not talking about special warfare. It is from Navy website. https://www.history.navy.mil/resear...abetically/s/sailors-as-infantry-us-navy.html It is talking about pre-modern times though. But I found it interesting. It is probably typical of most Navies around the world at the time. Basically for most of the history of human civilization, being a sailor is a lot like Black Sails or 300 Rise of an empire (Oh lord Eva Green). You will fight mano y mano. You will board ships. You will land on a beach and fight. And these are sailors not marines. cliff notes: Prior to modern times, use of sailors like infantry is considered major part of Navy's core competency. Regular training in small arms, boarding, landing parties part of everyday training. When US marines first created, they were very small in number and only used for small missions. Any large amphibious operations meant ship's crew is coming along. Not until 1933 did the fleet marine corp really take its modern shape. Up until around 1960, each ship depending on size had to maintain units ready for boarding, and landing. I wonder what it like in other countries. I dont think anyone else has a large Marine Corp like USA. What prompted me to look this is up, is I saw some vids of riverine patrols, and small boat operations, and of course watching Black Sails, and 300 Rise of an empire.
