Hm...you've decided on the Iron Warriors, and a good choice they are. Lots of powerful fire power, an interesting combat doctrine, and very little of that Chaos God junk to worry about. =D
Here are some recommendations for a 1500 point army:
-a modest Commander
-2 squads of Veterans...infiltra ting heavy weapons! use them to slow down infantry and light vehicles
-2 squads of CSM armed to be assault units who the Warsmith will go with. Or, if you want to spend the points, use your one Berzerker unit allowed.
-2 more static CSM squads for firebases
-either a Vindicator or a Basilisk (both Corrupted!)
-2 Predators: 1 for anti-tank, 1 for anti-infantry.
That'd be a FIERCE army with a lot of firepower, and a lot of staying power. Here's a practical list using those recommendations...b ut please try your hand at your own list!
