I played my first two games in 8th Edition.  They were a blast but I gut my butt handed to me.  Here is the list I took:

Company Commander- Plasma Pistol, Powersword
Company Commander- Plasma Pistol, Powersword
Tank Commander- Punsisher Cannon, Lascannon, Heavy Bolters
Infantry Squad- Plasma Gun, Heavy Bolter
Infantry Squad- Plasma Gun, Heavy Bolter
Infantry Squad- Plasma Gun, Heavy Bolter
Infantry Squad- Plasma Gun, Heavy Bolter
Infantry Squad- Plasma Gun, Heavy Bolter
40 Conscripts
10 Ratlings
Commissar- Plasma Pistol
Command Squad- Regimental Standard, Medipack, Plasmagunx2
Leman Russ- Battle Cannon, Lascannon, Heavy Bolter
Leman Russ- Battle Cannon, Lascannon, Heavy Bolter
Demolisher- Demolisher Cannon, Lascannon, Heavy Bolter
Demolisher- Demolisher Cannon, Lascannon, Heavy Bolter
Hellhound- Inferno Cannon, Heavy Flamer
Hellhound- Inferno Cannon, Heavy Flamer
2 Scout Sentinels- Heavy Flamers

It seemed like a good well rounded, all comers list.  I was wrong.  Not having played 8th before saw me make some tactical errors.  For instance having 3 units engaged by one Hell Drake.  First off, I wasn't aware that you only had to be an inch away to be considered engaged.  Little things like that have big consequences on the game.  I will learn and get better.  My list will also change as I get more models painted.  for now, here are a few pictures of one of the games.

Chaos in my face!!!

I hope you enjoy.
