Sherman Harrill shows several ways the
use of the Crescent Step in Isshinryu
can be used to attack the opponent's stance.
First he demonstrates how
he would disrupt an attacker
from the exterior line of defense.
what he did was to use the crescent stance stepping
to disrupt the attacker's stance
setting up a cross leg stomp kick.
Then he demonstrates
how the crescent step
could be used for an interior line of defense.
Sherman Harrill is using Garry Gerossie as his uke.
