OK that is already something
But still if we take the front corner, a block of 2 BWG TUG in column , will not be a block after the move as the new as the new "in line" frontage is less wide . It will still create a GAP.( the question has been asked to me )
Now if the 2 BWG UGS are side by side, forming a block and line. When the units receive a M9 order to create a column, they Will turn 90°( right or left, player's choice) . Now the new width will be more than the original width by at least one BW for each UG. How do we solve that move ? We push back the other UG one BW away of forward the first moved UG ? ( still can sent pictures if need be )
