"Move it! Damn it, do you all have brains as small as those of the Gnolls? How many times must I teach you that not only the warhorses need to move during a charge, but the riders must move with them!
You've got ten fingers and two arms, and they're not just for eating, wiping your ass, or entertaining yourselves!
Go back to the starting point and do it again!
This time, if anyone's movement is still not up to standard, I'll have you practice thirty more times! If one person in a team is not up to par, the rest of you can forget about sleeping tonight, you bunch of idiots!"
The rough and booming shouts of dissatisfaction echoed across the grassland as night fell, like an invisible whip lashing at the group of new recruits riding warhorses and practicing wall formation charges in front of him, forcing them to turn their horses and head back to the starting point without a moment to complain.
