• So, you're thinking about joining the military. Well DON'T! It would be the worst mistake of your life, of course what do I know I've just been in for 6 years. Whether your thinking about joining or just bored out of your mind and decided to take this stupid test, this is the best way to find out which of the 5 branches you should join. NO this will not tell you if you should go active or Guard or reserves.
