for only a single point, every veteran sergeant and officer should have at least a bolt pistol or bolter...
all officers should also have power toys as they are also a gloriously cheap price!
now if you want to be really daring, you can always try a power fist on those heroic senior officers - it's quite funny to see a marine player's face when they forget to target your officer and then you start killing his/her marines on 2's in an assault!
cheers!
