From listening to people who grew up with the veterans here in Norway I've learned that:
- Germans were told they came here to protect us against the British so they would - in the beginning of the war - shoot to suppress, not to kill. I guess Russian soldiers coming into Ukraine has been tricked to believe the "peace keeping" nonsense too and had a rude awakening.
- Norwegians however were already mad and shot to kill. I guess this holds true for Ukrainians too. This is natural and we've seen it in Afghanistan, Iraq etc too I think.
- German soldiers would cryingly admit to POWs already at the start of the war that they were absolutely not voluntarily there, they'd just be shot if they refused.
