Tank is damaged, tank crewman escapes. Then runs towards a friendly infantry position to get to safety. Infantryman is mad because their comrade led the Ukrainian drone to them. Proceeds to shoot guy who had previously escaped from his damaged tank. Third guy was unable to stop him from killing his comrade.
I wouldn’t put WW1 Germans and WW2 Germans in the same category. Yes, there was a good amount of nationalism in WW1 Germany, but they were hardly special in that regard.
