If Donald Trump is elected President, would it be more honorable to resign from service or to serve under his "leadership"?

MAJ Bryan Zeski, by the sounds of your question you have failed to truly understand what and who you are serving. You are serving to protect the peoples of the US and most importantly you are serving to protect the very document that gives us the law of the land and the rights of a free people, the Constitution. I served under Bush Sr., Clinton, W, and Obama. They all have their faults but that did not change how I looked and conducted business in uniform. I maintained focused on why I was there. Did I have my preferred CIC? Sure, everyone doe but, to give up because you disagree with whom the people's choice is pretty petty and weak. Both Bush Sr.And W. we're great for the military and national security but their ideas did have faults whether they knew it then . Clinton was good at getting our deficit under control but to what cost? The current occupant ran on "Hope and Change", well the change is in but there is no hope. The country is more divided now than anytime in history to include the 1940's when the government was collecting the legal immigrants from Japan, Italians, and Germany and placing them into "internment camps" or better known as concentration camps. The other time period was during the Civil Rights movement which as we all know, not a great time in our past. But to question whether to stay in because a business leader that does not play by the traditional political rules and he answers to only to himself is a worse fit than a community organizer with no leadership experience and has caused the widest divide in the nations history ever, maybe you should resign your commission. If you have that much doubt in your heart then you should be in a leadership position. That Sir is my professional opinion, not a personal opinion.

As many others have noted, your oath is to the constitution. If a US citizen, you have the right
to vote in the election of the President, Senators, and Congress Representatives. However once duly elected, you are obligated to follow the lawful orders of the chain of command appointed over you. Regardless whether of not you voted for a president or; whether or not you personally like or dislike the person in that office, you still are required to respect the office. As I have heard somewhere before, keep in mind after all that the job of president and all elected official is only a temporary job until the next election.

Seriously? You are going to ask that question when you've stated that those on active duty need to respect the office of the presidency? What I hear you asking goes against all the rhetoric you've been spewing over the current pResident.

I don't get on RP too often, but this thread jumped out at me when I logged on today. I see the standard reply provided by the Major Bryan Zeski; it's a rhetorical question. That's not a great response and it certainly doesn't provide the writer any cover in my opinion. I would expect a first term enlisted soldier or 2LT to consider posing such a question, but not a Field Grade Officer. Rhetoric or not, I'd say the writer would serve his command properly by resigning his commission now. Please do so before you're put into another command position and allowed to influence others by virtue of your position. Your soldiers, unit, Army and our great nation deserve better!

If I were still in the service, I would stay in. Although the President is Commander in Chief of the nation's armed forces, the questiona I would ask myself is who am I ultimately serving and why am I serving? And to honestly answer that question, which I did have to ask myself under Clinton, the answer was simple - while he WAS commander in chief, I was not serving for him, but because I love my country and I serve my country through my military service. In fact, I reenlisted while Clinton was president not because I believed in what he was doing, but that my military service to my country was BIGGER than any man (or woman) that would live in the White House.

If you are even asking this question you need to leave the service.

Your call to serve this nation shouldn't be solely determined based on who is president... Just an opinion only...

IMHO this is not an either/or position.
Both decisions and courses of action are honorable.
Your course of action will depend upon your personal belief and value system. It will be up to the individual to decide which path to follow.
There are some things to carefully consider before making such a critical decision (if you are in a position where you have this option (e.g. not under a service obligation or enlistment commitment), as one is only rarely able to simply resign and walk away.
- Go back and read word for word the oath you swore, not what you think you remember swearing to, but the written oath. Remember, the oath is different for enlisted personnel vice officers/civilians. - Consider the words of the particular oath and your motivations VERY carefully, -- think before you act. Resignation for reasons of conscience is noble and honorable. However, once you make that decision and submit your paperwork. it tends to stick. Resignation is bell you may only ring once, -- if you must leave, ensure you are doing so for the right reason.
- If you decide to stay and serve, again remember your oath and live up to it. If you have issues with the person, focus on the position (office). Once an individual is elected to the office and sworn in, if you decide to stay in, then you must serve to the best of your ability, -- again remember the oath. To do less than your best because you do not like the individual serving in the office is not honorable.

My political views have little relevance to my service. Unless something is a threat to The Constitution, I serve Commanders (including the CINC), that I may not agree with, but I serve faithfully and to the best of my ability.

I've never seen an officer (to my recollection its always an officer) that becomes derelict in their duties that wasn't wrong to do so...from the Army Physician in Desert Storm who refused to deploy, to the Officer who claimed our President (I didn't vote for the President, but he still IS my President and Commander in Chief) wasn't a legally elected official.

Seriously, people come and go (Trump could drop dead of a heart attack tomorrow) your honor and commitment is not to a person!!
