Starship Troopers by Robert A. Heinlein

A while ago I found myself somewhat fascinated by the Military Scifi subgenre. Turns out there's quite a bit of it out there. Luckily, I happen to have a friend who is into it. So he gave me a list of books to check out and Starship Troopers was at the top of the list. I was already curious because I've seen the film and the aforementioned friend HATED it. It was pretty good. Far bigger in scope than the film and why in the world would they leave out the mech suits!?! Those would be amazing on the big screen! Ah well, maybe someday they'll actually try to make a faithful adaption.

Aw, the movie is awesome in a "campy, tongue-in-cheek, propaganda-laden satire-of-militarism" way. Less so in a "true-to-the-source" way.

I think Starship Troopers III had the mechs. The sequels lose all the "deeper" satire and parody and actually do suck, though.
