If your Battle-Pilgryms need some air cover, the Vultarax Stratos-Automata is a floating weapons platform. Suppress enemies with an arc blaster, fire horde-slaying airburst, and tank-wrecking shaped charge missiles, and cut up anyone who gets too close with vicious talons. Its speed and ability to fly over intervening units and terrain mean you can get that deadly weaponry exactly where you need it on the battlefield.
