The Hydra Flak tank is a newer (though not exactly new) vehicle based on the ubiquitous Chimera chassis for the Astra Militarum. It appears to draw inspiration from several real world anti-aircraft tanks such as the Gepard and Shilka, though it uses an open topped turret more reminiscent of earlier vehicles. I honestly liked the look of the vehicle, and thought it would fill a niche as an anti-flyer vehicle in my Astra Militarum Brood Brothers detachment, so I decided to take the plunge.
