Rebecca and I played a small (700 point) 40K game last night, her with Orks and me with my Imperial Fist. Her army looked something like this:

Warboss with 5 Nob Retinue (mixture of Choppas, 'Uge Choppas and a Power Claw) in a Trukk
2x15 Slugga boyz w/Burna boy on foot
2 Warbuggies (1 x MegaBlasta, 1xTL Rokkit)
1 Dread (Big Shoota & Scorcha)

My force was:

Chaplain
2x10 Tac Squad (Heavy bolter, Missile Launcher)
Bikes (3 x Reg, 1xAssault)
Tornado

She crushed me. I had one unit left (the Tornado). I couldn't stop the Warboss... She rocketed him up in the Trukk in turn 1 (I tried to pop it but failed!). In turn 2, she assaulted with the Warboss & Nobs -- and that was pretty much it. My Chaplain managed to take out the Warboss, but died doing it. I killed maybe 1 Nob. While that was going on, her Slugga Boyz advanced under fire and assulted me. It was sick.

I LIKE orks. I want more orks. Mmmmm, assault.
