How the Strategic Radio Silence been maintained externally in those days ? Was it literally Silent , practically for the Tanks during War 2 , in general .... ?? Help me to get some general Idea .... Speaking truly , its very interesting to me whenever I go through the incidents like ...... maintaining their radio silence ... ,, not to break radio-silence there .... or like by breaking their radio-silence ..... etc. What they actually do there,waiting for HQ Call or something else ..? @ ! Really I've no Idea over there .. How long they had to maintain it ?
