There was a time when even many high officers earned their Nahkampfspange or Panzervernichtungsabzeichen - close combat clasp and tank destruction badge, this is of course also a sign that something went wrong :-)

Is for an infantry/tank officer an university education during his/her fist 9 years really a good idea? From an academic POV it does not make sense.
If an officer decided to leave after 12 years, he/she should attend university during his last 2 or 3 years, then leave with a "fresh" graduation/diploma. If an officer decides to stay he could get an military graduation, i.e. staff officer courses.
