Vantaggi
Diverse work experience. Almost every Soldier has a unique career path. As a 35P, one can pursue a strategic, tactical, "stratical", or any combination of the three flavors of mission related work. You can work the gammut, from missions that directly/indirectly support the NSA to those that support the US Special Forces, Rangers and other special missions units. The US Army pays for the entirety of your training, which also counts as college credits and provides ongoing tuition assistance (about $4000/yr) for the school of your choice throughout the duration of your active duty career (then there's the 9/11 GI bill, an additional $50,000 for education when you get out). As a 35P, the DoD will pay for you to obtain a swecurity clearance, that will also open up other career paths after the military. As a new enlisted Soldier on active duty, the Army will provide all necessary food, lodging and work uniforms while in training and at your first duty station if you remain single. Promotions come fast as long as you have a strong moral compass, do the right things, give 110% effort and stay out of trouble.
Svantaggi
The transition to civilian life after the military is not easy. They're totally different cultures. But as long as your willing to go the course, you won't regret it!
