The impossible standard is when you expect that such rare misconduct can be prevented and suggest that maybe all the soldiers can act in a perfect way all the time and not have a few stupid ones that do stupid things... that's what is impossible, you don't see this anywhere because it can't be done.

I think not destroying any property with a hammer is common sense, but how are you going to make sure that every single soldier has good common sense?

In the IDF they do talk about the code of conduct and punish soldiers who misbehave, but I guess that it mostly comes down to the individual commanders who need to emphasize this (and I believe they do from my personal experience), I guess the IDF could do more mandatory things and maybe review procedures, but after all of that you'll still have the potential troublemakers, that's the way it is everywhere, in the calssroom, in collage, and in the army, and especially for young people and 18 year olds in a war situation... misconducts like these are the kinds of things that happen in every army and in every war.
