Most of his stuff is more fantasy than scifi depending on how you define them. His main series is Monster Hunter International. It's about a band of mercenaries that hunts monsters for the bounties paid by the feds or private parties. It's good fun. He has an epic fantasy series hes working on, Saga of the Forgotten Warrior based in an world with an indian like caste system. There is a diesel punk sorcery trilogy set right before ww2 that is a bit more series than his monster hunter series but not quite epic fantasy. Hes got a few Mech books out too. I havent read those yet. Hes big into gaming and has a miniatures board game on kickstarter based on his MHI series.

Baen is his publisher. If you're looking for non-cucked military scifi they have a ton. I'll usually pick up anything with a baen logo I see at a used book store even if I havent heard of it.
