I've gotta agree with ya hairy.
At this size game numbers are everything. More bodies for the blood god and that jazz I suppose.
We pay quite a bit for 'rines, so cut down on the expenditure list.
On the captain drop the melta bombs and the bionics (your never gonna use it my friend). Drop melta bombs on the tac squad, can you give them a melta. (you might meet something out there that requires this (insta-kill a crisis suit or two, that falcon grav tank zipping round).
I would actually consider dropping the dread full stop and roll in another to squads (5man tac and 5 scout - snipers this time)
And the rhino - drop the pintle stormbolter (you get one for free - why take two?) and drop the hunter killer and pop some smokes on - few points saved there
Now back with new listy....
