None our soldiers were forced to join the U.S. forces, they did it because they felt some kind of calling.
Not necessarily true. I have served in the US Army for 9 years - active duty, national guard & reserves (currently). People I know have joined for many reasons. These include:
- a calling or sense of duty (as you mentioned)
- college money
- looking for adventure
- economic necessity
- a path to citizenship
- "go to the Army or go to jail" - yes, some people in their late teens/early 20's are still given that choice in court
I joined up initially for college money & adventure. I reenlisted in 2006 out of a sense of duty as well as pursuing another avenue for retirement benefits.
