First, talk to your brothers. They will give you the straight scope (or at least I hope they will.) Second, we are at war and you should be expecting to go to war. Don't fool yourself about some MOS's don't go, etc. You need to be ok with being in Iraq or Afganistan and pulling the trigger. When I joined the Navy, the LT who signed my up told me straight out "If you are in the Navy, you will go to sea." I'm telling you if you are in the army, you will go to war. Finally, be sure to take advantage of all the college options for servicemen. We have a pretty good GI bill now, so if you do the time be sure to take advantage of it.
