This is a teeny tiny lore 'bug' that I'm sure most players will ignore, but to me it's a bother. In the Story Arc Collateral Damage, Petty Officer (Assuming 3rd class) Laura Lockhart addresses you as 'Sir' before informing you that you were given a temporary rank of Sergeant.
First off a Petty Officer is Naval including Coast Guard Rank, SGT is what the other forces, like Army and Marine, use. And unless she's PO3 (Petty Officer 3rd Class, which is what the others call Corporal), she's ALSO equivalent to a SGT on up. In fact, she might outrank you is she's a Petty Officer 1st Class.
Also, in the American military the honorific Sir is solely used for Officers, like Lieutenants or higher. Petty Officers and Sergeants are Enlisted, so you call them by their rank, which in this case would be Sergeant.
I know most players, and even roleplayers wouldn't care about such a tiny thing, but the only reason I went down this rabbit hole is because one of my current characters is former U.S. Army and I'm one of those losers who cares too much about lore and want to get the 'backstory' right.
If I have a suggestion, it's to change her rank to Corporal and have her call you Sergeant in place of Sir. IF possible. Otherwise, I will suck it up.
Thank you for your time.
