I'm afraid I have more questions on this topic. I had a game last day and my opponent pointed out that single elements are simply ignored in the new marching rules. Let's look at it in detail.
The first sentence seems clear. No one can march within 400p of enemy group not beyond friendly fortifications. Here comes one of the key factors pointed out by my opponent. Only groups are specified, not enemy elements. This means that my elements ignore enemy groups, not single elements.
And then comes the long list of exceptions in which only friendly groups can march on under all conditions detailed there. The problem is that enemy single elements are not specified anywhere!
I mean, what happens when my single element is within 400 p of an enemy element? This case is not included, apparently. Enemy groups (other than the exceptions) stop marches, enemy single elements stop friendly groups not moving straight ahead. But what happens when single enemy elements are whitinh 400 p of my single element?
All opinions would be appreciated.
