Pros
The Army has opened up so many doors of opportunity for me. I have been able to travel all over the world and meet all kinds of people. The Army pays my room and board as well as all my medical bills! It is not hard being a soldier in the Army - you just have to do what your told to the best of your ability. Respect those superior to you. Live by the Army Values. I am proud to serve my country. I have never regretted enlisting in the Army a day in my career and I never will - even through some of the rough times - and yes, you will have them, but those are what make you a better soldier.
Cons
Downsides of the Army? There aren't many. If there are they are petty things that don't really matter too much. The deployments can be long and tough and they can take a toll on you, not just physically but mentally and emotionally. It's easy to get frustrated but most of the time you have to grin and bear it.
