Which is a better choice of career the Military or Police Force?

The original question was worded as:

Which is good Military or Police Force Military is usually athletic. Besides Military I can join Sports or Martial arts. Martial arts are including Karate Kung fu judo and all that. Both organizations are physically active. Both allow for participation in outside groups, such as sports teams and martial arts. I have worked out with a number of police officers in my martial arts classes. Both organizations often sponsor teams that play in various leagues.
