Should a 2LT salute a 1LT?

See 'B' above. This isn't a debate.

No.

As my commander told me when I was a young lieutenant.....rank among Lieutenants is like virture among whores

My commander told me when I was a you Lt. "Rank between Lieutenants is like virture among whores" so no you don't salute

2LTs should know everyone is watching them. If they don't salute their superior officers, why should that SSG salute that 2LT who is probably 5 years younger than he or she? In other words... lead by example lieutenants- in all that you do.

Uh, no. Just like WO/CWO don't salute any lieutenants. Its a common courtesy among officers that you don't salute if you only have one bar. Anything advice that the rule doesn't apply.

The way the regulation reads, it could be interpreted as being that officers should salute amongst each other, and enlisted should salute amongst each other as well. As such, a PV2 should salute a PV1, etc...it could also be interpreted to mean that the only time a salute is rendered is when an enlisted person salutes an officer. I did not read deeply into AR 600-25, but it seems to be vague regarding the definition of who is entitled to a salute. This really falls into traditions regarding customs and courtesies, and I believe the regulation provides some structure to that. As LTC Gene Shewbert stated, the salute is a right (military prisoners are forbidden from saluting, they have lost that right/privilege) and should be delivered with that in mind and as a sign of respect to the rank that has been bestowed on that person. With that said, although I don't have a problem with a 2LT saluting a 1LT, I think that requiring a salute among personnel that should be working as peers may, in some instances, create an undue strain, particularly when that brand new 1LT, who is still not very experienced, lets that "requirement" go to his or her head. In addition, it is sometimes just difficult to tell if the approaching officer is equal or senior or subordinate when it is LT to LT.

Yes. It is a respect for the authority of those appointed above the rank. A 2nd Lt. is junior in both rank and tig, therefore rendering a salute is only proper.

In the Marine Corps we have the "one bar rule" where WO's, 2ndLts, and 1stLts dont salute each other UNLESS they hold a position above you. Every Marine Officer goes through TBS which is 6 months of training on top of the months of waiting to start or from being injured (which is very common) then you head to your MOS training which means a lot of officers dont hit the fleet until they are 1stlts or even Captains so during the training period lts are all in the same boat sitting in the same classes together

Wow. So much thought and discussion to something so clearly spelled out in military regulations and tradition. The salute is more of a respect from one soldier to another than a recognition of rank. However, the respect and requirement to follow legal, ethical, and legal orders like the standing order (regulation) to salute seniors. All junior officers salute senior officers, no matter what their rank --- unless it is in combat or at places where it has been waived by the commander (like active combat, sniper infested areas, flight lines etc.). There is nothing wrong with a senior soldier initiating a salute if the junior has not yet done so. In most cases, it is the men junior in rank to me that I have admired most. I always knew that the men working for me and with me would do their best to keep me alive. It was a few of the fools above me who I thought might get me killed one day.
