Well stated my fellow warrior

So true.   They went way to far towards the ww2 German salute. Well minus the German navy. They refused to do the Nazi salute. 

Oh lord, the less said about the First Order salute, the better. :C

ORIGIN OF THE HAND SALUTE
No one knows the precise origin of today’s hand salute. From earliest times and in many distant armies throughout history, the right hand (or "weapon hand") has been raised as a greeting of friendship. The idea may have been to show that you weren't ready to use a rock or other weapon. Courtesy required that the inferior make the gesture first. Certainly there is some connection between this old gesture and our present salute.
One romantic legend has it that today’s military salute descended from the medieval knight's gesture of raising his visor to reveal his identity as a courtesy on the approach of a superior. Another even more fantastic version is that it symbolizes a knight's shielding his eyes from the dazzling beauty of some high-born lady sitting in the bleachers of the tournament.
The military salute has in fact had many different forms over the centuries. At one time it was rendered with both hands! In old prints one may see left-handed salutes. In some instances the salute was rendered by lowering the saber with one hand and touching the cap visor with the other.
The following explanation of the origin of the hand salute is perhaps closest to the truth: It was a long-established military custom for juniors to remove their headgear in the presence of superiors. In the British Army as late as the American Revolution a soldier saluted bv removing his hat. But with the advent of more cumbersome headgear in the 18th and 19th centuries, the act of removing one’s hat was gradually converted into the simpler gesture of grasping the visor, and issuing a courteous salutation. From there it finally became conventionalized into something resembling our modern hand salute.
As early as 1745 (more than two-and-a-half centuries ago) a British order book states that: "The men are ordered not to pull off their hats when they pass an officer, or to speak to them, but only to clap up their hands to their hats and bow as they pass."
Whatever the actual origin of today’s hand salute, clearly in the tradition of the US Army it has always been used to indicate a sign of RESPECT – further recognition that in the profession of arms military courtesy is both a right and a responsibility of every soldier.

Do they salute in the Star Wars universe?
 
The clones did during the war.
 
 
Clones kept doing it after the war.
 
The clones saluted old commanders.
 
 
The rebels would offer salutes.
 
 
Imperial officers would offer salutes.
 
Imperial pilots would offer salutes.
 
The First Order would ju....... you might want to use your discretion with this one.  
 
Opened up some books on customs and courtesies.  While there are minor differences between armed services and services across the world, many of the same basics are the same.  I'll offer some here and if you know some, please share what you know.We have a number of prior military people here that know it better than any book.

And do keep your right hand free.  You never know.

Australian Navy.
 
The personal salute with the hand, although borrowed from the Army, is full of interest and various theories have been evolved concerning its origin. There is the usual theory that it has been the custom from time immemorial for a junior to uncover to a superior, and even today men of the Brigade of Guards remove their caps instead of saluting when wearing fatigue dress. The holders of this theory maintain that the present salute is merely the first motion of removing one's head-dress. It was officially introduced into the. 1~Jtavy in 1890, but during the war a large number of old retired officers were in the habit of doffing their head-gear instead of saluting, this, of course, being the method to which they were accustomed.
In a book called ‘New Art of War', printed in 1740, it is stated that - When the King or Captain General is being saluted each officer is to time his salute so as to pull off his hat when the person he salutes is almost opposite him'.
Another tradition is that the salute and its return were given as mutual tokens of trust and respect, so that when two armed men met they both raised their visors, thus laying themselves open to attack. The old head-dress being clumsy and not easily removed, the preli4nary movement of the salute was considered sufficient.
That the hand is kept open is probably a relic of' very ancient times and denotes that no weapon is concealed therein.
The salute with the left hand was abolished in the navy in the year 1923, so as to bring our customs into line with our allies and also to conform to the practice in vogue in the Indian Army. Both on the continent and among Indian and African troops a salute given with the left hand was considered a gross insult.

As you can the origin details very service to service but many of the details are common regardless and it is never confusing I am in the Australian Navy but I work with a US Army unit in Hawaii we salute superior commissioned officers regardless of country.

This is how is the Army Salute in Australia.
 
Salutes are reciprocated at the highest levels up to and including Heads of State and are indicative of a feeling of mutual trust and respect.
The exact origin of the military salute has been lost in time but it is believed that it originated by showing that the right hand (the fighting hand)
was not concealing a weapon.
Another explanation is that when men-at-arms took to wearing armour, the approaching generals or king would ride forward and, holding the reins of the horse with the left hand, they would raise the visor with the right to identify each other.
By the beginning of the nineteenth century, the salute with the hand palm to the front was firmly established.

Congarts on the reapproved costume!  It looks Sharpe!

When the command bridge view ports were compromised. The ships E.A.P.S.  (emergency atmosphere pressure shield) engaged. Ok I just made that up , but for (b.s.) it sounds official. Right?

I just assumed with Ezra force-pushing the door and vaguely in Thrawn's direction, that he'd be holding off the vacuum with the force for their hyperspace jaunt. It makes about as much sense as any other force-related nonsense

I second that. The man is awesome when it comes to being open and talkative with us.

There may remain a question of power though, as it appears the reactor was destined (at least damaged).  There may well be emergency countermeasures that could have been triggered, given a number of the bridge stations seemed to be in operation.
Another possibility is the nature of the hyperspace lanes themselves.  It could be within the realm of possibility that there is a form of atmosphere while in hyperspace transit.  That is, of course, pure supposition on my part.
I do wonder how they survive, but I am beyond ecstatic that they did.
 
Who knows, maybe we'll see Ezra, Vanto and the Grand Admiral come to the rescue of the Resistance in Episode IX...

If a star destroyer could throw up shields to keep the atmosphere in when it’s hull is pierced (as it did in the first season), I am sure the bridge could too.
 
now a whole ship crashing through the bridge? That’s a horse of another color 

Star Wars and physics in space travel have never really mixed though. Swooping, diving fighters, &c.
 
I mean we can make up hand-wavey superscience explanations, but at the end of the day, it's not realistic. But it's great, nonetheless.

You know, I was rewatching the last episode with my kids. And WELL, there is a loop hole in our theories.  I noticed for the tentacles to be inside the bridge that the glass had to be broken. And Ezra even lifted it using his force powers. It was all over a couple of shots.   And I know that in reality, if you are exposed to space you die.   So even in hyperspace.  You would be exposed to the vacuum of space.  I think they accidentally killed Ezra and thrawn.  So, now in my head if they show back up. I'm going to want an explanation of how they lived the vacuum of space and at hyperspeed to boot!
 
 
Stinking physics! Always getting in my way!  Just like gravity being my greatest foe.   Its always dragging me down in life
 

Yeah, I didn't like that either. But Hollywood science is magical.

It was the space suit thrawn had in his back pocket the whole time. :). But I would love to see the explanation.  I'm still thinking moving at or faster than light speed and no space suit on. And how long before they stopped. I'm just being nit picky. I'm a firm believer in the laws of physics and space travel.

For me, one of the best parts was the acknowledgement from Dave in Rebels Recon that certain characters are indeed alive.
Plus a very quick nod, for those who caught it, to a certain Captain now brought back to Canon.

Cool. My email address is cubscoutsOhiogmail.com or bobafearthefett@gmail.com 
 
Either one will work. And if the file is too big I can get you my unlimited work email.

Awesome, I was a staff Sgt. Us army.  I did well on the asvab too. Just decided to go traditional infantry like my great uncles and grandpa and brother. I should have gone to college. I would be in a better position today. But all in all, I'm glad I am where I am. My kids mean everything to me.  Scouting is like icing on the cake.
 
 
But I am going to find a way to get some other 501st, rebel legion or MMCC guys \ gals out to the event. I am hopeful it works.  This could be a superbly useful event for us. It could open doors to more exciting adventures for the 501st.  I have been asked before to lead a survival skills event for one of the big summer camps near Cincinnati. So if all goes well. Maybe it could be another 501st event.  No fire of course. (Plastic melts)
 
But any more thoughts are highly welcome. And any IOC members are most certainly welcome on April 14th.  Its at cricket holler scout camp in Dayton Ohio.  Its going to be a fun morning. :). And I'll feed you too!
 
Thanks guys!
