Ralph Peters, the author of the superb Cold War era novel of WWIII,
Red Army (written from the Soviet soldier's POV), is putting out a new novel which looks like it could provide some inspiration for T2K (all iterations) campaigns. It looks like it's about a post-nuclear exchange conventional war where the fighting as devolved to a decidedly low-tech level. I haven't read it yet so I can't give it a review but it looks pretty interesting and I really enjoyed
Red Army.
It's called
The War After Armageddon. Here's a link to Amazon.

BTW, I'm a little embarrassed to admit that I'm just now reading
Starship Troopers for the very first time. I'm enjoying it so far. I also just finished reading
Ender's Game, another sci-fi novel exploring war in the far future. It's targetted at young adults but I found it pretty intense and mature in tone and content. Both it and
Forever War are essentially anti-war novels so it's interesting to read Heinlein's novelistic counterpoint.
