I agree with both of you, Soren and Juha. But, my response was to Lucky's original question, and was aimed at the NORM among all armies of WW2. Yes, soldiers, in particular in some units more than others, were trained to act on initiative, and to sieze opportunities. However, the overall command structure was still predominant. My mention of the (original) S.A.S. was as an illustration of the BRITISH army at the time, three years into the war; Stirling's ideas, and methods, reinforced and expanded by the core group he assembled, were AT THE TIME, totally unique to the 'standard' procedures of the BRITISH forces, who, in general, were still entrenched in outmoded ways.
I am fully aware of the qualities of the German armed forces at the time, and of the individual in particular, and would point out that the methods employed by the German forces during WW2, especially the period(s) of 'Blitzkreig', are included in the instruction at various levels of today's British forces. Afterall, it can be said that the German forces at that time totally 'redesigned' the rule book as far as 'modern' warfare goes. Until then, the idea of total and flexible cooperation between elements in the field had not been properly implemented, and the use of air power, for example, in support of ground operations, was born in 1939-40, courtesy of the German armed forces. But, to confirm, my initial response was to Lucky's question about combatants allowing freedom etc., to which my immediate answer was "..as in Nations, I know not." Therefore, as far as my initial response is concerned, I would argue that I am not "completely wrong".
Not having been around during WW2, I can not comment with authority on what might have ACTUALLY happened as regards the intended structure of orders within a chain of command in the British army, but, as a former member of Britains S.F., (in more modern times!) I DO know that the lessons learned, from ALL sides in that conflict, have been noted and absorbed, and have, in the British army as in others, where appropriate, been written in to 'the book'.
I trust this clarifies any misunderstanding you might have regarding my response to Lucky's original question.
Regards, Terry.
