Hint:some of these events involved spheres of influence and control over resources in eastern europe!
EDIT: If you understand German, here is a song from 1972 about these brutal cross-examinations:

Additionally, the participation of Germany in the first aggressive wars in Yugoslavia in 1999 and then in Afghanistan from 2001 on (before citizens were told that the Bundeswehr is only a defense army, and would never participate in an aggressive war) lead to a radicalization of another generation against the Bundeswehr - and yes, this generation eagerly listened to the above-mentioned horror stories of the older generations. It is even rumored that this next generation's radicalization against the Bundeswehr indirectly lead to the suspension of the compulsory military service in Germany in 2011.
Tbf, at least in West Germany people had a choice. In East Germany you ended up as 'Bausoldat': https://de.wikipedia.org/wiki/Bausoldat, and you could forget about any 'carreer opportunities' for the rest of your life.
And as former East German who then went the 'Kriegsdienstverweigerer' path in unified Germany during the 90's I cannot complain about any discrimination or incorrect behaviour, all communication was perfectly correct and respectful and I didn't even have to show up anywhere in person (in hindsight it was a silly decision - but in the 90s it really looked for a little while like the Cold War might be over and armies would no longer be needed in Europe).
In the 90s, the situation was already very different - doing alternative national service (Zivildienst) instead of compulsory military service got a lot easier (possible exception of which I heard: you were very athletic - it was rumored that then they still made it much more inconvenient to refuse to do military service).
For good reasons, my references were from older generations - the trauma that they had to endure if they wanted do alternative national service (Zivildienst) instead of compulsory military service exactly did lead to the situation that it got much easier in the 90s to do alternative national service instead.
