Ironclad has solid hit boxes, good accuracy with melee, and a hand weapon that's capable of putting serious dents in Khador 'jacks.
Despite lacking the nigh-excessive survivability of their northern red neighbors, the Ironclad can take a few solid hits, especially when you factor in that there is really only one arm you need to be especially concerned about. Some of the best strategy that's worked for me with the Ironclad is immediately moving it into combat with the biggest 'jack in your opponent's army, or getting it entrenched with a lot of short-range targets. This negates the main problem involved with losing movement abilities and, to be honest, with the Ironclad's above-par MAT, losing its cortex isn't much of an issue, either.
Used in conjunction with jacks or casters who can inflict Knockdown on the Ironclad's target makes his tactics almost too simple. Auto-hitting with a significant bonus to damage means that almost nothing can stand against this 'jack for too long.
I'm assembling a Stormclad at the moment, for use in conjunction with some Stormblades I have yet to paint up and complete assembly on, so we'll see if this guy gets replaced or simply becomes a necessary adjunct to my lists.
