What is the best order to issue when the enemy situation changes but your mission remains the same?

When the enemy situation changes but the mission itself remains the same, issuing a fragmentary order (Frag order) is the best course of action. A Frag order is designed to provide timely updates and modifications to existing plans based on changing circumstances without the need to reissue the entire operation order. This type of order is typically brief and focuses specifically on the adjustments needed in response to the new enemy situation while reaffirming the original mission objectives.

The Frag order allows for a quick dissemination of necessary information to the forces involved, ensuring that they are informed of any changes in tactics, enemy movements, or other relevant details that may affect how the enduring mission is executed. It helps maintain the momentum and clarity of operations, enhancing the unit's ability to adapt to battlefield dynamics without unnecessary delays that could arise from more comprehensive orders.
