If you watch the little dudes in OIE, you'll see that they can change pose depending on the gun without affecting the animations, also they aim at their target - like twist their waist and lean back or forward to suit. The dudes .x file has no weapon poses, I had to make my own poser thingy so I could set the limb angles inside the engine.
I did this by leaving the arms alone on the animations, then manually rotating them to suit - if you animate the walk but not the arms, you don't need to keep rotating the limbs, it remembers them because rotating a limb on an animated model is like an offset, it stays like that all the time. Once you have the limbs posed properly, you can rotate the waist any way you want.
With a single mesh object, you can get decent movement without duplicating animations or writing your own system, the important thing is to plan it all out.
When Lee get's his finger out and fixes the LIMB DIRECTION commands we'll be throwing models around ragdoll style
