"Welcome to the business end of the Liberators, sir!" so Besk wound up being the first one to throw the Lieutenant a salute. The guy might have been a volunteer, or maybe he was assigned there, but it made sense to keep the new Lieutenant relatively happy even if the Liberators had a strange way to their military method. For example, Valerin almost made faces, almost, at Besk's beard -- that'd been a conversation in the past.

[i]"What's the meaning behind the beard, trooper?" the man asked, Imperial Army correct, all the way.

"It's my Liberator beard, sir." 

"What do you mean?"

"It means that I intend to shave it off when we get to Uslam and kick the Empire off it, sir!"[/i]

That was the last he ever heard of it from the captain, though he hadn't been the first one to think of growing a beard -- it was a fast and easy way to tell friendly from hostile in a fight, because the Empire didn't do beards, but it also caught on as a fashion statement, along with longer than regulation hair and sideburns and various forms of facial hair. Even the aliens started adopting it, the ones that could. 

In any case, they saw the Captain's back quickly enough and that was to the relief of everyone involved. Besk was tempted to give the new arrivals the spiel about a weapons function check, which also doubled as a way of assessing the skills the new arrivals had with their blasters, but decided to save it. So uncomfortable silence reigned for a moment after he saluted the Lieutenant.
