(3)     All Officers must consider the action to be taken by the men under their command in the event of penetration of their trench by the enemy, and will think out a plan of action and take necessary precautions to see that overland routes are familiar to all.

Company Commanders must always be prepared to refuse their flank and be in mutual agreement with Units on their Right and left.
