Tirone Thunderers are Imperial Guard regiments raised from the world of Tirone. Collectively known as the Thunderers, Tironian regiments come in great variety of artillery, engineer and logistics units, training their whole supply chain by themselves. As per order of Departmento Munitorum, Tironian regiments have been armed by nearby industrial worlds of Dimlight Stars since time immemorial except for their fabled Thunder-Blaze cannons which are hand-crafted on Tirone.
