Today he took a big long test to earn his E4 rank (err, rating?... i get confused). That means he would be a petty officer. It also means that he would get to change from stripes:
To a chevron:
(except that instead of anchors I believe he has the insignia for ET which is a helium atom.)
He doesn't know how he did yet. All he knows is that it was "HARD!". And that he had to share a test with another guy because they ordered the wrong tests for the ET's. Go Navy!
Monkey has promised to share more later.
