So lets pretend you are talking about germany and the ussr . I would draw 3 front lines of my basic infantry . One in the north , one center , and one south . I would give them either no attack order or an attack order set to minimum aggression . Since it sounds like you might not know what that is you can just use no attack order . I would then take my mechanized or attack infantry higher soft attack variant with more artillery and split them into smaller groups . I would draw short front lines on each of the three zones i made earlier . I would draw attacks of the same width or less about 3 or 4 tiles deep . Try to draw pincers that connect in the rear . Here is a snapshot i found on googleimgrefurlofironiv 45 thdevelopmentdiary 19 thoffebruary 2016 . 909353 % 2 FdocidWyV 3 f 0 xkNhJXLMtbnid 9 HZsSxGDYxbrqM % 3 Avet 1 w 1920 h 1200 bih 974 biw 1920 ved 0 ahUKEwj 63 sHk 9 cLQAhXk 7 YMKHSwCA 64 QMwgmKAkwCQiactmrcuact 8 I would have drawn a shorter attack myself and tried to link up with another one when possible . The next time you draw an attack order hover over the arrow . It will show the tiles your army plans to take and in what order they plan to do that . When you have a very wide line with a very wide goal they don ' t attack effectively and you can see that . A simpler way of doing all of this is to just draw one huge front line of like you mentioned and manually move an army of armor for penetration on smaller fronts . But try it the way the image shows and you can manage bigger wars .
