An excellent sci-fi war novel from the viewpoint of a grunt. This novel has very little in common with the movie of the same name. This book is more akin to "Platoon" in space than anything else. The reason is because it's essentially Heinlein retelling his experiences island-hopping during WWII with a futuristic twist. One of his best books.
I have read a couple Heinlein books now. I love his writing style. Having seen the movie, I expected the book to be similar but better. This went leaps and bounds beyond my expectations! Heinlein had a lot more to say than "Kill the bugs!"
