Well I don't have the Fallen Realms book to hand at the moment so can't give you an exact list, but here are things that I personally would at least try to include:
Demolition Troops with Bombs,
Maybe an Isengard Troll if you can fit it in. Then fill out the rest of the points with standard fighting uruk-hai (remembering you're also going to need a few heroes to keep in check with the warband rules.
If I can get hold of the Fallen Realms book, I'll form a more useful response.
