Check out this mech:
This is the XV95 Ghostkeel battlesuit, the latest in Tau stealth technology. And the one that Games Workshop's weekly magazine is doing action shots of, decloaking inside the Cadian lines, has a female pilot. Plus, the model has a feature where you can pop open the cockpit and put a pilot figure inside, and it includes a female head for her (with a Y-shaped nasal opening instead of an I-shaped one).
Even better? This week's issue confirms that a female head is included in the new box of Fire Warriors. The one that also comes with the new pulse shotgun weapons, the MV36 Guardian Drone, and the DS8 Tactical Support Turret, plus pieces for markerlight drones. <3
These are our most basic troops, the ones pretty much every Tau player will buy when they're just starting out. And you can model one helmetless soldier as a woman, one who wears the same beat-up armour as everyone else and is doing the same dangerous jobs.
Our faction's fluff already said we had gender equality. But in practice we rarely saw female representation in models, Shadowsun notwithstanding. I once had an opponent put up a fuss about being corrected on my models' pronouns, despite the fact that he also played Tau and he knew that we fielded Fire Caste troops of all genders.
Obviously, there's still a long way to go before women can be considered "equal" in 40k, both at the gaming table and on its imagined battlefield. But this is an amazing first step. I'm so proud of them :')
