maybe its the same.
but my soldiers are inside the dropship.
and i only bring 3 or 4 at a time.
with this image, notice that the cursor is not a box.
i think this indicates that the cursor is on a space soldiers can't move through.

i think this indicates that the soldier cannot at this time move to that space - because it is blocked or out-of-range.
