The Brit Generals were often more dangerous to the troops than the enemy was. If the war had gone on any longer the surviving UK generals in High Command would probably have been replaced by Australian and Canadian Commanders.

Shellfire was the #1 killer. Counter battery fire based on electronic processing of shock waves and muzzle flash played a big role in eliminating German guns. General McNaughton played a key role in developing that, saving the lives of thousands of troops.

McNaughten also played a role in the early development of Radar and Radio Bearing finders. 

During WW2 he put into place a Canadian industrial infrastructure that manufactured mobile radar directed anti-aircraft batteries long before UK and USA industry could do the same. Once again saving lives under attack from the air, or lost in the sky not knowing the way home.
