60% of the US Military branches have Starship Troopers on their reading list!
Starship Troopers, is an incredibly popular science fiction novel, and it's legacy has stretched into the depths of modern militaries. Over fifty years after it was first publicized, Starship Troopers can be found on the reading lists of the United States Marine Corps, the United States Navy, and the United States Air Force. It is the first science fiction novel recommended on three out of five military branches.
Some of the policies that the military has adopted straight from the book, is the idea that the military should be an all volunteer, high tech strike force. When the book was publicized, military forces were almost all conscripted, and Starship Troopers changed that.
In fact, the book is so influential on the United States military that in 2002, a marine General described the future of marine corps uniforms and equipment as "needing to emulate the Mobile Infantry", the soldiers from the novel!
