Basic Law for the Federal Republic of Germany
The Basic Law also created a soldiers' ombudsman or Wehrbeauftragter, reporting to parliament not to the government. Soldiers can write directly to the Wehrbeauftragter if they feel they have been treated unfairly or unlawfully, or if they think their commanders are acting illegally.  Soldiers cannot be punished for writing to the Wehrbeauftragter.
