How long would it take to be commissioned as a 2nd Lieutenant in the Army?

Once you have completed all of the requirements to become a Officer, you will be commissioned as a 2nd LT. That means you have completed your College Education, OCS or ROTC, and all the other training. Once you are commissioned, you will be igned a branch (Combat Arms, Transportation, etc). Army Rangers is nothing more than a special group of Soldiers. Dont get me wrong, they are a elite group and not everyone will make it through the training. If you happen to complete the course, you will be labeled as a Ranger and get to wear a special tab on your uniform to identify you as Ranger qualifed. The rank structure does not change, if you are enlisted (Private, Specialist, Sergeant) or Officer (Lieutenant, Captain, Major) it stays the same. Lastly if you are writing a novel, a female can not be a Ranger at this time. They are looking to change the rules, but i think it is far away.
