[Corporal Punishment]

i don't think you need quite so many grenades on the HQ, krak suck and are redundant with meltabombs anyways. as for the tac squads, equip your sarge like the rest of em, they seem pretty shooty so give him something shooty too, otherwise he'll just be polishing his chainsword the whole time without doing much good. while plasmas are a good idea, especially against hordes, you may consider making a few of the squads CC buffers for whatever makes it through your fusillade. making the landspeeder a tornado (HB+AC) would be a good idea too, it will scythe through those 'nids like a howitzer in the front row of a Britney Spears concert. but how does your list work for you? i assume you think it could use some improvement or else you wouldnt post it here.
