well, It wont help versus vehicles, but I know how to up the affective range of the sob's to 36". deploy squads of 6, and make one of them a heavy bolter. that will make them a better shooty army, but they will still play better if you do other things. Thinking from that perspective though, I dont actually know what those better things are. I just cant keep the sistesr out of assault AND get them close enought to shoot with the maximum affect. I find that if I dont move forward, my army just gets shot up. if I move forward, then my army gets shot up and none of it servives the close combat that ensew's.
