There isn't much of a difference as the Marines are both water and ground based Only major differences are ranks, boot camp is harder in Marines, and Navy is all Sea.
There's no difference their both under the Department of the Navy.
You let your enlistment with the Navy expire and then join the Marines. There is no 'transfer' between the two units. If you are a Corpsman, you can be asked to serve with the Marines.
The Navy is part of the armed forces. Their job is to protect the shipping lanes of it's respective country while Marines is a branch of Navy and they're tasked to know how to kill.
Spanish Navy Marines was created in 1537.
None. Navy Seals are all Navy. Marines are a completely different branch of military.
Inter-service cooperation exists between all branches, although the Marines do traditionally have a much closer relationship with the Navy than the Army does.
The Esperanto word for navy is mararmeo but there is no word for marines in Esperanto.
Marines are part of the military, many will argue that the Marines are the best/highest trained military branch in the US military (now im not saying that there arnt special forces for other branchs that arn't better then Marines, all im saying is for basic training i'd have to say that the Marines are the best)
This may come as a shock to you, but the US Navy SEALs are under the Navy and not the Marine Corps
The motto of Spanish Navy Marines is 'Per Terra et Mare'.
The Navy
The Royal Marines are a part of the Navy. They're the "go anywhere" amphibious infantry. They are also part of Britain's Rapid Reaction Force and considered by many to be among the top combat infantry soldiers in the world.
