Hey guys,

Today I bought this and being a brand Warhammer 40,000 player I think I'm going to need some help. I want to make a true-to-background Imperial Guard force that is also balanced on the table so i ask you good people:

1. I have twenty Imperial Guardsmen and three Heavy Weapon Teams, how should go about assembling them?

2. The Command Squad; what should i put in this for it to be effective at average size games? (It won't be a Platoon Command Squad)

3. The Sentinel, it will definitely be a scout, but what weapon are they usually fielded with?

I know this sounds odd, and i do have the Codex, i was just want the opinion of veterans to save me several hours of arm dismemberment .
