John Ringo – Aldenata Series, Black Tide Rising series, so many others…
Michael Z. Williamson – Freehold (and the other books in the same setting), Better to Beg Forgiveness (and others in the Ripple Creek Security series)
Tom Kratman – Carrera series
David Drake – Hammers Slammers series, RCN series, Bellisarius series, many others (and some fantasy too)
Jerry Pournelle and Larry Niven – Anything by this duo, from Lucifer’s Hammer (which is probably one of the best asteroid impact stories) to Oath of Fealty and others.
…more as I think of them…
