finally! another guard player that uses the cross.
i take it you're using the stormtroopers as suicide tank killers? in this role 5 is more than enough. if you want them to try to grab a late game objective it might be worth adding a few more troopers but i'd stick with what you have.
i'd think about swapping the plasma guns in platoon B's hq to melta gun which can fire on the move better, allowing them to keep up with the flamer toting infantry squads.
i'm not a big fan of the vets. i feel that bs4 is too good to waste on measly grenade launchers. i plunp for 3 plasmas and a las cannon in mine and lay the smackdown on transports and MCs. i get the feeling yours are directed more at infantry right?
i don't like the snipers either, 3 just ain't enough. my money is on the demo charge for these guys. a little unpredictable but very effective when it works.
all in all pretty nifty
