ABSTRACT
When engaging in warfare, if the enemy is cast in the role of the host while you are acting as the guest, you should concentrate upon penetrating deeply When you have made a deep penetration of their borders, the enemy, being the host, cannot be victorious because you will have attained the situation of the terrain being heavy for the guest and dispersive for the host. A tactical principle from the Art of War states: "When you penetrate deeply, the troops will be unified."
