I am looking for some millitary sci-fi along the lines of John Ringo, or Heinlein. I enjoy the large scale millitary engagements and was wondering if anyone out there can recommend some. I have also read the Luna Marine books. David Weber's Honor Harrington series was great. Any thoughts on power armored infantry style millitary sci-fi. I have also read a great number of the Warhammer 40k books. The Guant's ghosts novels were good but I find the imperial marines less exciting because they are bio-engineered to have no fear, that kind of weakens the thrill a little. Thanks.
