"Once again you refuse to provide as scrap of backup to your own claims and dismiss out of hand documented evidence put up" - Jim Carroll

What the fuck do you think this is you gormless Prat:

Crozier's books were controversial for their claims of doubtful factual accuracy. He was largely discredited and considered a nuisance by the contemporaries. - SOURCE - Walker, Stephen (2007).

By the way glad you brought up Harry Patch who by his own admission in the interview he gave the BBC said that he had never encountered anyone suffering from shell shock so could therefore have never seen any summary execution by any officer of anyone suffering from it - could he?

As to Officers turning guns on or threatening their own troops, the following iis cut'n'pasted from Harry Patch's interview:

Mutiny

'E' company were about a thousand strong. We had an officer we didn't like. He used to take us out route marches. We didn't like it. That afternoon he wanted the 'E' company on parade for bayonet practice. The war had been over for months. The sergeant major opened the door. Somebody threw a boot at him. He went back, reported it.

The officer came and they told him flat that they weren't going out on parade. Well, he went back to the company office and about thirty of the men followed him and they asked for him. He came out, he pulled his revolver out and he clicked the hammer back. Nobody said anything. We had all been on the range. I was on fatigue that morning so I wasn't on parade. Nobody said anything.

They all went back to their huts and they rounded up what ammunition they could and went back and they asked for the officer again. He was a captain, risen from the ranks. He came out and he clicked the hammer back on his revolver. He said, 'The first man who says he is not going on parade, I'll shoot him.' No sooner had he said that, when thirty bolts went back and somebody shouted, 'Now shoot you bugger if you like.' He threw the revolver down, disappeared. We were all run up for a mutiny.

We had a brigadier come over from the mainland to hear the officer's side of it. Then he said, 'I want to hear the men.' Twenty or thirty of the men went behind a screen and they told him. They said, 'We don't want bayonet practice. We've had the real bloody thing. Some of us are wounded by bayonets.' The outcome was that there were no parades except just to clear the camp, just fatigues. The officer was moved to a different command. We never saw him again. It's a damn good job we didn't.

Now those were men out of the line and in no danger. Do you honestly think that under fire they would meekly allow any Officer or NCO to shoot them without a murmur and then keep quiet about it? Utterly preposterous and totally unbelievable.
