Women in the Guard are very common in the lore but not in the models, so converting is pretty much the only option.
Legs and torso are Cadian. But I shortened the legs by sepeprating them from the 'skirt', chopping a bit off and reattaching them.
Her arms and weapon are from Les Grognards from Wargames Atlantic with a laspistol tip and half of a pair of binoculars as a scope.
The head is from Victoria Miniatures.
The arms are a bit slimmer than standard cadian ones and the hands aren't huge mits, combined with the shorter legs gives a suitable look for a woman in military kit.
I've always assumed that the imperium only has the
STC fragment to produce one size of uniform, armor and boots.
