Should a 2LT salute a 1LT?

That's the rank structure, 1lt is by rank the higher in the rank line so yes he should salute.

Yes.

I spent 31 years in the Marine Corps made it to MGySgt. And after I retired I put my uniform back on because my nephew had just been selected and promoted to WO in the Army And he asked me if I would attend. I thought it was an immense honor to be able to salute this brand new WO and show how much I respected what he did. I only wish I could have attended the ceremony when he became a first lieutenant, second lieutenant, captain, and now major. I think the BG said it all above and nothing else needs to be said about should whether you should or shouldn’t salute someone. Great answer General.

Salutes is about honor and respect for each other.

When I was a young Captain, a 1LT in my housing area berated a 2LT who lived next door to her for failing to salute when he got out of his car in his driveway and she was outside. As an officer and an AF brat, I was embarrassed for the 1LT for her teeny weeny self-esteem. Positional authority is the weakest kind. Think that 2LT (or anybody else who witnessed it) had ANY respect for her?

That non come who complained had barely put on his stripes but did get the respect afforded to the rank. Non cons need to practise what they preach and if we can all preach from the same manual our military will be so much better...On the minute.

Yes but not absolutely. The regulation aside for a moment. It all depends on the type of environment the officers are operating out of. An example must always be set and assumed enlisted are viewing the professional exchange; always lead by example, set the example. If the officers are under a professional development course among fellow officers, respectfully no, especially if they are on a first name basis. A very senior 1LT or in command such as Company Commander, Platoon leader etc... yes, please salute.

Different branches have different instructions, but I’m surprised this is even a question. Of course a salute should be rendered, and the junior should initiate the salute first. Common sense should tell you that sometimes people don’t notice, aren’t paying attention, have thier hands full, etc...

The problem I have is when an enlisted member renders a salute, you know darn well the the officer saw it and is fully aware and capable of returning it... but doesn’t. At least in the Navy, returning a salute is NOT optional, but some junior officers either are unaware, or have thier own opinions on the matter.

1st Lt is a command executive officer that usually is subordinate to a Captain, so my question is, if two Lt's are standing side by side, are they equal to a Captain NOW? How's that old saying go? Ours is not to wonder why, it is to do or die?

This question ties into officership. As some have stated, the Marine Corps will follow the One-Bar Rule. Lieutenants and Warrant Officers do not salute each other. Bottom line, it’s awkward. At The Basic School, you have 2ndLt, 1stLt, and WO1 all running around together as students and peers. Because we grow up together in that regard, we don’t think of ourselves as superior to one other. That’s not to say that we don’t show respect to that CWO4 or CWO5 or the 1stLt, but we don’t salute each other.

In my class, we even had a Capt who was a staff judge advocate. Just how it works for them with commissioning and going through law school. So he was not a fleet Marine yet. We wouldn’t formally salute him because we were all on the same level. It would just be awkward and isn’t warranted in that setting.

Bottom line, salute the position and not necessarily the rank when it comes to officers. If a 2ndLt and 1stLt are both platoon commanders, why would you salute each other? Now if that 1stLt is my Co Cmdr, I would absolutely salute out of respect for the position or billet held.
