Right i've taken the advice given into consideration and I have come up with the first semi-serious list, there is a lot of stuff thats in this list that is simply redundant or just plain bad, but thats there for fluff reasons (and while its not going to be set in stone, i'd like to keep some of these elements).
Ok then... the list...
Lord commisar (ciaphas cain), carapace armour (which is 'forgot to return to the stores'), camo cloak (to represent his always trying to stay alive) and a power weapon (I know he only has a CCW but hes a world class swordsman so I figured a powerweapon was a reasonable upgrade to represent this).
CCS, carapace amour, krak grenades, medi-pack, vox-caster (not needed, but IG always have them), meltagun (jurgen).
Colour sergeant kell
Lord castellan creed (rorkins)
Bodyguard x2
Master of ordinance (brasker)
Master of the fleet (visiter)
Infantry platoon:
PCS, medi pack, platoon standard, vox-caster, heavy flamer.
Platoon commander, bolt pistol, power fist.
Commisar (donal), power fist.
Infantry squad, vox-caster, flamer.
Sergeant, power weapon.
Commisar (nels), power weapon.
Infantry squad, grenade launcher.
Sergeant, power weapon.
Infantry squad, vox-caster, flamer.
Sergeant, power weapon.
Commisar (stebbins), power weapon.
Infantry squad, grenade launcher.
Sergeant, power weapon.
Heavy weapons team, autocannon x3.
Heavy weapons team, lascannon x3.
Heavy weapons team, lascannon x3.
Veteran squad, grenadiers, vox-caster, heavy flamer, flamer x2.
Sergeant Bastonne.
Total: 1500.
The infantry squads will run as blobs of 20 with a commisar leading each blob.
Let me know what you think, and any areas you think that can be improved, also any ideas for increasing the force to 2k points.
*Edit*
I've gone with the cadian forces as I feel that these represent the majority of the pdf forces well.
