Looking for some criticism on this list I made, i'm not looking fordward to blow the leaves on my local store, since chaos is my main army and this
IG is to move now and then from the often gameplay i use. However i'd like to stand a chance

, i used to do a really crappy list with lots of chars and
GK termies just to throw some dice, needless to say i've never won with that list, so i decided to pimp it up a lil, make use on tanks and shooting goodness (which my chaos army lacks).
So this is what i came up with, what do you guys think?
HQ 340 pts
CCS with straket, standard, vox, medipack, meltagun, carapace armour, 2 bodyguards and astropath on chimera.
Troops 688 pts
Veteran Squad with harker, vox, 3 meltas and demolitions.
PCS with commissar, 2xPF, vox and 3 snipers.
Infantry squad with commissar, 2xPW, grenade Launcher, vox and heavy bolter.
Infantry squad with commissar, 2xPW, grenade Launcher, vox and heavy bolter.
Infantry squad with grenade launcher and heavy bolter.
Heavy weapon squad with 3 lascannons.
Elites 317 pts
10x
PBS on a chimera.
7x stormtroopers w/
PW
3x ratlings
Heavy 655 pts
2x Leman russh squad with heavy bolters
Colossus w/enclosed crew
Manticore
My main idea is to let the guardsmen squads with their heavy weapons back on the table on cover along with the snipers while straken and his friends move fordward on the chimera to get in time to support harker and the stromtroopers as soon as they get on the table while sending barrages and using the
PBS to pin/fall back key units.
