Advertisement for the army?

So here is a question: As far as I know doctors in Germany are not allowed to advertise freely and there are tough regulations on advertisement…. but I have to constantly see that advertisement for the German army that looks more like a first-person shooter video game?!?

During a games convention in Cologne the whole city was full of video-game like advertisement to join the army and to “do what really counts”… in “Mali” “[saving democracy]” for “our country”…

Wouldn’t it be nice if doctors are also allowed to freely advertise?
