Conqueror

Thunder Warriors were somewhat closer to Eversor Assassin than normal post-Unification Space Marine. They were berserkers made for brutal combat in post-apoc wastelands Mad Max/Fallout style. Obviously less tactically versatile than Space Marines made for space crusade where they have to deal with different issues and actually think quite a lot. Thunder Warriors were much simple-minded guys. They just used A LOT of brute force, often in melee just because of scarcity of ammo. The Emperor gave them only a small part of His glorious brawn. But definitely not the brains.
