Drill

The agent starts out of measure in Quarta, the patient in Tertia. The agent advances one step, gain the weak of the patients sword. The agent to advance another step in order to strongly constrain the patient’s sword. The agent’s right foot should be aligned with the patient’s left (as per illustration 7). There should be strong pressure on the patient’s blade. As soon as the the constraint is complete, the agent will begin to extend both arms forward and down. As arms near full extension, the body inclines. By this point the agent’s left hand should be controlling patient’s blade while the point goes under the patient’s hilt. Complete the attack with a step such that the front feet are aligned.
