But you move the left foot to the right.... not to the left. ;-)
(how long depend on your drill book)
Since the distance to the man in front is not a big issue Iam not sure it is something that is that relevant to add.
But having a step to the left and to the right would both be useful.
The right when in line, and both when skirmishing and you are standing behind a tree and want to fire and then move back into cover to load.
