When someone decides to go into either the military or law enforcement they commit themselves to a field that offers little in the way of options for a lateral career moves. People join the military for however many years they choose to serve and, once they separate from active duty, there aren’t any options for them to come back. There is no option to spend five years in the Marines, leave the service to spend time working in another field, and then return to active duty. Yes, there are the reserves, but that isn’t the same as being a full-time member of the military and isn’t really what I’m talking about here. A Non-Commissioned Officer (NCO) in the logistics field cannot go work for FedEx for a few years, learning new skills and new ways to do his job, and then come back into the military and bring those outside influences in. From what I understand about careers in law enforcement, the same dynamic exists, that once a police officer decides to leave the force, only very rarely are they able to come back in.
