Most people who look for careers or starting points in their lives never consider the humanitarian effort of the US Army. You can become a veterinarian in the Army which is extremely important during these humanitarian efforts. Livestock is wealth and a source of income for many people in other parts of the world. Keeping animals healthy will certainly build cultural bridges.
Many WP grads will command and lead reserve units before leaving the Army and its worth the considerations when thinking about WP and a career in the military. Their commitment is 5 years active duty and 3 years reserve after graduating from WP.
Any commissioning source can result in follow up education. Most medical specialties have a humanitarian mission. I guess I just don't understand this post...
