You sure about the Sergeant rank? It doesn't quite jive with his personality.

Edit: But it's up to you. Just that it's a bit of a leadership role and all.

Edit: Also, PLX-2 is a little too new-tech, maybe an old school Republic PLX-1? Those were known to take down AT-ST's with a well placed shot -- lots of power. Either that or the good ole Rebel HH-15, which was harder to aim and required a better touch to get it right.
