As of now, I am not actively pursuing a military career of any sort. In the past I had been interested in the guard, reserves, and active duty (all branches). Recently, when I was telling a friend about the specific unit - direct app. - process that the guard and reserves offer, he asked if "national guard" were defense only missions. I wasn't sure what the correct response was. My assumption was that it was basically a question of manpower. If the military needed guard manpower overseas, then they would go. However, I wasn't sure if they regulary deployed, especially since many pilots are part time.
Any info you might be able to share would be very interesting to me. Thanks!
