Volkites, amusingly, weren't actually that powerful IIRC. Like, they did a ton of damage, but were fairly short-ranged and not good at penetrating armor. So they're the idea weapon for CQC against fleshy enemies, I could see them being amazing at Tyranids and Orks in a space hulk, but despite being a rare tech they're not necessarily inherently better than bolters for everything.

Yeah, Thunder Warriors were only meant for the campaign on Terra itself IIRC, cause the Emperor literally didn't trust them to be able to sit still on a spaceship long enough in between conquests to not start making trouble.
Honestly the contrast between the Tau and the Imperium is fun because it's a study on two fundamentally different ways of doing warfare. Do you treat the common soldier as disposable chaff and focus on uplifting a handful of elite troops to get the missions done that cannot be completed by throwing waves of disposable fodder? Or do you focus your efforts on supporting the common soldier with as much support as you can give, and rely on making regular army elite and well-equipped, foregoing separate organizations of supersoldiers in favor of making the regular military stronger?
