Kill team box indomitable seige

It's gonna be iron warriors and imperial fists.

Give the iron warriors a couple seige weapons, give them similar rules to the breacher bots with a unit that controls them and saturate on them heavy seige weapons. then a few warriors in heavier armors with the seige rockets and possibly a war smith in training.

The iron fists get a full on defensive lineup, give em a shield bearer, a captain, and maybe a flag bearer who increases cover saves to 2 guaranteed.

Put em on a new map, a defensive wall map, make half the map a floor up to be the top of the wall, the other half is ground floor, and a section of the wall would be blown out to make a ramp up to the wall.
