Pros
No doubt being able to complete missions is the most satisfying part of the job. Some missions are really rewarding and worthwhile. At the end of some days you can feel certain you did something positive. The pay is good too. No 18 year old kid, unless he's a computer wiz, will get paid what an E-1 in the military does, and officer pay is very good. Some of the leaders we have a truly amazing people, outstanding role models for junior personnel.
Cons
That being said, most of your days will not be so rewarding. A great deal of your time will be spent spinning in circles because the senior leadership can't figure out where to go, or what it wants to do. You'll also be away from home and family a great deal. Expect to miss MANY holidays and special days (birthdays, and such).
