Here is a Kill Team I used last night to a reasonably level of success.
Imperial Guard Stormtrooper Squad
Imperial Guard Veteran Squad
Comes to exactly 200pts
For the three USR's, I gave the Stormtrooper Sgt Fleet, so he can Deep strike, Shoot some AP3 death and then charge with a power weapon.
Secondly, I gave the Veteran Sgt Furious Charge, just because.
Finaly I gave the Sniper Relentless, because who doesnt like no-scoping people!
It is a small skirmish game where you are capped qt 200 points and everyone is seperate from the squad. So if you had an imperial guard squad with a heavy weapon, the squad cqn move up however it wants and the heav weapon team can stay in the back
