Starship Troopers is a must read for all ages. It proposes political and philosophical concepts as well as military training and strategies. It weaves all these themes together in one impressive book. A lot of people that gave ST a bad review didn't even seem like they read the book. This book is also original. The political and philosophical concepts in the book seem like they are of Heinlein's creation, but not his personal belief's. READ THIS BOOK.
