“What a Shinobi Should Keep in Mind to Know the Enemy: It is essential for a shinobi monomi [covert scout] to speculate deeply about the way the enemy is. However, you should not report what is not reasonable enough to report. The commander in chief, troop commanders, or strategists make their strategy about the enemy based on the information given from the above covert scouts. This is critical to defense; whether the information is reliable or not is of vital importance.”
