Still in the vein of military sci-fi, I finished Hammer's Slammers by David Drake, and quite liked it. Drake has a way of writing war stories that emphasizes the realities of the troops on the ground, and how those same troops become policy makers, whether you want them to or not. And for a story released in '79, it has held up remarkably well. Easily on par with Haldeman's Forever War in terms of writing and relevance.
