Well, Cave Mother encourages orc women defend their lairs and husbands but unarmed (or wielding anything what would count as warrior weapon). They can use bows, slings or other hunter instruments while hunting but not in combat. As overall Gruumsh based orc culture places women outside warrior culture entirely. But it makes sense the women of the tribe work as crafters, healers, medicine women and so forth. Mystical arts are not limited to men (and some powerful female mystics like Razura can climb very high in social ladder by sheer mystical power alone and be considered a asset in battlefield). But physical warrior engagement is left for men mostly but women can use claws or improvised weapons to defend homes.<br/><br/>But if you want up and honest homeguard; they must be made from men. Or women who are more physically fit and have improved unarmed strike as one feats (or have plain monk levels if take them into 'home guard' slot in warrior resources).
