I've been playing a bit different last few games, running an aggressive assault army. So far, it's worked out pretty well, but won't work against everything.

Still, the idea of playing in-your-face is nothing new with Orks, but the new book allows for a level of durability never seen before from the boys.

Battlewagons, ho!
I've talked about Warbikes and durability.  Well, it wouldn't take much to really exploit this. Add in some troops in battlewagons and you will be playing the whole game on the other side of the table.

Ork Horde Detachment (2000pts)
Warboss, PK, Da Lucky Stikk, Warbike, bosspole
Painboy, Warbike, bosspole
Painboy, Warbike, bosspole

20 Slugga boys, 'eavy armor, Nob w/ PK&BP

The one downside is not having any protection for the battlewagons, from like a KFF but hopefully some cover will be available. It's not an issue if you go first however.

But two full units of bikes, both with FNP and one with WS5 will be a huge threat.  But with the warboss tanking with his 3+ cover rerollable and FNP should mean that turn of shooting will be pretty much for naught.

The meganobz add in a little punch for tougher units, and after they get out you can always move a painboy over.

Orks have always wanted to play on the other side of the table, and now they might just be able to pull it off.
