Feeling guilty about not joining military?

The military is in shorter supply of medical doctors than soldiers. If you want to serve your country and your friends, plan to complete your medical training and apply for a direct commission. Thus, by completing your medical training you are serving the greatest needs of your country and friends. And who knows, once you've completed your education and residency, your country and friends may need you more as a civilian rather than a military physician. Only time will tell.
