Pros
If your looking for a place to find your technical skills and learn to work around problems then this is for you. Overall your view is going to be VERY much part of where you work. Some will love their job others will hate it. It gives a great chance for growth in abilities.
Cons
Leaders can at times not fully understand their jobs thus making your life worse You don't just have to do your job, it is a "crew" ideal Promotion is sketchy at best while you can always make rank it is is in many cases based entierly on the time you have spent in not on how hard or good you work. Don't be fooled your not hacking away at computers or tearing into the newest things on the planet your most likely working on 40+ year old gear that is falling apart or takes 100 parts to do what your cell phone does.
