Just asking because I’d always heard Navy personnel in TV and movies say “Aye” or “Aye aye”…but tonight on JAG I’m quite sure a Marine said it to a fellow Marine.
Would that ever really happen in a Marine unit?
I’m not military, but I know that the US Marines are a branch of the US Navy. Um, for reasons I don’t understand. So, anyway, the sharing of traditions is understandable, right?
Yes, the US Marine Corps is part of the navy and does share some terminology such as “aye aye” to acknowledge a command. The marines have been part of the navy since revolutionary days and no one has ever seen a need to make them a completely separate branch of the military as was done with the air force after WWII. A lot of training is separate such as boot camp but marines attend the navy academy, officer candidate school and many enlisted specialty schools
I’m 99% sure The Marines have their own OCS. UncleBill should be able to confirm if he happens along this thread.
As for aye aye, it just means “yes, yes.” I don’t see why Army or Air Force, or anyone else for that matter, couldn’t say it as well.
Again, we’ll wait for a sailor or a Marine to be sure, but I believe that ‘aye, aye sir’ carries the meaning ‘order received and understood’, whereas ‘aye, sir’ means ‘yes’. So:
HR: ‘Make your depth 50 meters.’
LR: ‘Aye aye, sir’
HR: ‘Have you field-stripped your rifle today?’
LR: ‘Aye, sir’
Based on 3 years in the Navy (admittedly, some time ago) you are correct. I think the most accurate translation of “aye, aye” is “I understand and will comply.”
Nice to know I’m appreciated.
Navy and Marine Corps Officers do go through the same Navy ROTC system if they go that route, but virtually all Marine Officers need to complete OCS (Officers Candidate School) and TBS (The Basic School) at Quantico, VA. The Navy counterparts (in Navy ROTC) do not complete an OCS.
Naval Academy types (Navy style) also do not attend Navy OCS. The Marine-style Naval Academy people at one time did not attend Marine OCS, then they did (mid 80’s) for maybe a year, then they didn’t. Now I don’t know what they do.
Other commissioning paths into the Naval Officer ranks include a 13 week OCS at Pensacola (candidates apply while in college or soon after) for Line Officers, complete with getting yelled at and sweating a lot.
But if you are a doctor, lawyer, or some other specialist, you could get a Direct Appointment, and not go to OCS at all, but Officer Indoctrination School (OIS) at Newport, RI. No yelling or sweating at OIS.
Basic answer, Marine and Navy Officer candidates do not co-mingle at any OCS.
The U.S. Marine Corps (USMC) is not part of the U.S. Navy (USN). Both are in the Department of the Navy, though.
The USMC is headed by the Commandant of the Marine Corps (a 4-star general), and the USN is headed by the Chief of Naval Operations (a 4-star admiral). Neither reports to the other. Instead, both report to the Secretary of the Navy (a civilian), who reports to the Secretary of Defense.
In other words, the Department of the Navy is comprised of more than the U.S. Navy.
In my experience, “aye, aye” and “aye” are used interchangeably, to mean “I understand and will comply,” as stated by Xema. Navy sailors can properly answer “Yes, sir” and “No, sir” when responding to direct questions from superiors, however, as in your second example.
BTW, in your first example, any Diving Officer of the Watch (DOOW) on a U.S. submarine would get an immediate response of “Repeat back the order!” from the Officer of the Deck (OOD).
The exchange actually goes:
OOD: “Diving Officer, make your depth 150 feet.” [Note: we don’t use meters.]
DOOW: “Make my depth 150 feet, aye, sir.”
Then after the sub is at the ordered depth:
DOOW: “Sir, my depth is 150 feet.”
OOD: “Very well.” [No repeat-back necessary.]
This is a very good system that eliminates any chance of confusion, particularly when the OOD is giving out multiple orders to various personnel.
For example, if the DOOW mishears the order, the exchange goes like this:
OOD: “Diving Officer, make your depth 150 feet.”
DOOW: “Make my depth 250 feet, aye, sir.”
OOD: “WRONG! Diving Officer, make your depth 150 feet.”
DOOW: “Make my depth 150 feet, aye, sir.”

erm, this isn’t exactly true. I hate to burst you guys’ bubbles but:
you see, when we see aye aye we are really paying homage to our leader, Daubentonia.
cough
[sobers up a bit]
xema pretty much hit the nail on the head 
Speaking as an ex-Army grunt, the US Army does not use or officially recognize the term “aye.” Any soldier that does say aye in response to an order would be on the receiving end of a great deal of shit and questions about their lack of intelligence that they don’t know what branch they belong to.
That’s exactly why I brought it up. I really thought it was only used in one branch of the service.
Very interesting. I appreciate all the replies.
If I may offer a clarification, the concept of putting “marines” on Navy vessels wasn’t invented during the American revolution, but actually dates back to when the British Royal Navy recruited some 1200 soldiers to serve on warships in 1664. The main functions of those marines were to:
[ul][li]Defend the ship against boarders[/li][li]Board and sieze other vessels, and[/li][li]Disembark and attack land targets including towns and forts and whatnot.[/ul][/li]
Anytime you see one of those “Horatio Hornblower” movies (set during the Napoleonic wars), the guys in the red suits are marines. They don’t participate in the day-to-day activities of running the ship, but those are the guys you need when the swordplay starts.
The Royal Navy was copying the Dutch navy. The Dutch Marines are the oldest marine force in the world. Just a clarification.
:rolleyes:
This is my understanding. The thing is that “aye” is just a synonym of “yes”. Think here an officer might make a comment looking on shore and says “That chick in the blue dress sure looks cute.”, to which a sailor with him might respond “aye”. In that context there are no orders involved that need to be carried out. However, if the officer says “Make your depth 50 meters.”, the response is “Aye aye, sir” to make it clear it was understood as an order. “Aye aye” is VERY unnatural use of language, which is exactly what would be wanted in the case of a response to an order to clear up possible confusion.
To expand upon Bryan Ekers excellent post, Marines were also used offensively in battles by putting them up in the rigging and shooting down onto the decks of other ships. This is how Lord Nelson died, although I don’t know if those French shooters were officially called “marines” (or the French equivalent). Also, IIRC marines were used as a “police force” on ships - any time the captain ordered anyone taken to the brig the marines would do this.
Fair enough, though the rolleyes was unneccessary. The original post said “since revolutionary days” (the 1770s, one assumes) and the reality is that marines have been around much longer.
Further to what Bryan Ekers has already said, one of the most important duties of the Marines (Royal Marines from 1804) in the Royal Navy was to prevent mutiny. The crew could not be assumed to be charitably disposed towards the officers, and Marines were accomodated between the crew and the officers. Marine sentries stood guard outside the Captain’s cabin, and at the quarterdeck.
Even in the US Navy, according to DR. WILLIAM S. DUDLEY .
In general, Marines would be armed with muskets, while sailors would be issued cutlasses before going into action.
UncleBill you forgot that students can skip the ROTC in college by joining the PLC program. They spend two 6 week basic training sessions during the summer and then are commissioned upon graduation.
Along with “Aye, aye”, Marines use many other terms used in the Navy, such as; bulkhead (wall), deck (floor), head (restroom), cover (hat) and skivvies (BVD’s).
Any Marine will gladly tell you that the Marine Corps is older than the Navy. 
Those 2 six week sessions (or one 10 week session) for PLC is still OCS, not basic training. I didn’t go through all of the commissioning routes, since this thread was dealing with where Navy and Marines can cross pollinate in training. There is also OCC (Officers Candidate Course), and ECP (Enlisted Commissioning Program), but those don’t do anything with Navy candidates, either.
