When there is a small body of enemy troops (say only 4 inches away) which are heavily outnumbered it seems overkill to make the larger unit wheel around before they can charge and engage (if they have enough movement left after wheeling !)
I think there should be a break ranks rule to allow the 1st rank (or file - depending on the enemy's location) to peel off the larger unit and engage as though they were skirmishers until the larger unit catches up.
What do you think ?
