DSII: Split Unit

 I just bought DSII and went quickly through the rules. Is there any way
to
split a unit without it becomming DISORGANIZED?
 In case I am not clear, start with a large unit of 10 Heavy Tanks. Is
there a way to send 5 of the tanks in a pincher to the left and 5 of the
tanks in a pincher to the right? 
 If there is not, why would you not start with 10 units of 1 tank each?
