Thank you very much for detailed explanation. I'm disappointed - the only way is placing units far away (long distance=late arrival),but it's very primitive method for such complex game.
I noticed other imperfections in editor: minefield can be add only in editor (minesweepers and minelayers can't do it?), enemy bases can't be captured (grief, it could be substitute of dynamic campaign). I am surprised that so extensive and long game-series has so many shortcomings.
And, unfortunately, I do not know how run HC editors under Win10
Thank you Herman, I am pleased that you have devoted so much attention to me.
