Finally got the chance to complete these models. Not the best representation of their ilk ever modelled - the boots don't quite look right on them for one - but they make a cool Grenadiers tank-hunting squad that suits the look and feel of my army immensely.
Was a fun kitbash. I debated using Fire Warrior Shoulder Pads on them, but they just didn't feel right, and sometimes felt a bit obstructive. To be fair, even my Shas'la don't wear them, so that's my personal preferences showing through more than anything.
