I've met a few soldiers who have gotten off work up training to deploy overseas (for various reasons) because they
-Didn't feel the work up training was challenging enough
-Weren't given the respect they deserved as a warrior
-felt they were under employed
-Should have been given more critical jobs/tasks
-Felt their skills were wasted.
Mainse, if you've felt that your college and university level classes were too easy that you're either
-too smart or;
-full of crap.
Either way. Even if you think certain checks in the box, like say high school diplomas are below you- others won't think that way.
Not having a highschool diploma won't restrict you from joining the infantry but it WILL throw you a curve ball when you attempt to get any kind of employment outside the military.
One a side note, not many dudes join the infantry and 17 and stick with it until 55. Give it some though.
Another thing to ponder.. 9 times out of 10 when someone is homeschooled and joins the military you can pick them out in a crowd.
