@jmkorhonen.fi Maybe one more reminiscence is allowed, as this subject about different military systems now came up.Long time ago I was driving in the area of operations of an international peacekeeping mission. Was going to someplace, but not sure about the route.A roadfork ahead, and a peacekeeper private standing guard there. He was from a faraway country with professional military system. Very good:– Good afternoon, soldier, do you speak English?– Yes, Sir!– Excellent. Can you please tell me, if this road to the right leads to so-and-so-place?– Yes, Sir!– Thank you very much. Good bye.I got lost and never found my intended destination. Afterwards asked from a colleague of mine, an officer from the same country as the private, what might have happened. Turned out it was my own fault. In that country’s system, a private cannot say no to an officer. Instead of a stupid question, I should have asked, which one of these two roads leads to where I am going.
