Thanks Gibsomn for the explanation about detaching/attaching units.
I have played with Rock, Scissors, PaperProPE (Original v.3.019).sce again.
And I have noticed something strange.
When I make new route and connect it with waypoint 47,
my platoon should go to waypoint 47, then go to waypoint 28, then 31.

However, they just stop at waypoint 47, even after I take control and press "c",
they still won't move.
why?
I have tried a few times, the result is the same.
Then, because they won't move, I make a new route to 28.
Now, they move.
However, after reaching waypoint 28,
they won't go to waypoint 31, but circling endlessly around it,
and as the result, they always get killed by enemy tanks up north.
I set tactics on "march" from 47 to 28, then "engage" from 28 to 31.
What is wrong here?
