Talk to a recruiter and see what it's all about.
You will find that when you are in a situation, there really isn't time to think about what you are going to do. You will rely on your training. You will rely on your fellow officers. There is no time to panic. Sometimes there's no time for discussion. You work with other officers long enough that you will come to know how they are going to act, and they will know what you are going to do. That sort of training and teamwork is reinforced very strongly in the military.
Additionally, military experience will put you at an advantage when applying to these types of jobs.
best of luck!
