See Ya, Butter-Bar

Aaron got promoted to a First Lieutenant from a Second Lieutenant.

Doesn't army rankings seem backward?  There's got to be a reason but I haven't found it yet.
Second Lieutenant (gold bar), aka Butter Bar
    > First Lieutenant (silver bar)
        > Captain (two silver bars)
            > Major (gold leaf)
                > Lieutenant Colonel (silver leaf)
                    > Colonel (silver bird), aka Full Bird...

I am getting ready to pin on Aaron's new ranking.
We did this in the middle of the battalion meeting.  And I don't know what I'm doing. Awkward.

Salute from his commander, Major Duryea.
