Spoiler: New concept for Invictus

Tumbril Storm
Manufacturer: Tumbril Land Systems
Focus: Combat
Originally introduced in 2606 during the Second Tevarin War, the Tumbril Storm single-operator mini-tank was built to blitz battlefields and take out enemy artillery. Reimagined from the ground up to be faster, stronger, and more impactful than ever, the latest Storm is a true force of nature, well-suited to the frenetic landscape of modern warfare.
