What technique should be used when adjusting fire close to friendly positions?

Creeping fire is the correct technique to use when adjusting fire close to friendly positions. This method allows for gradual increments of fire towards the target while ensuring that friendly troops remain safe from potential friendly fire.

Creeping fire involves firing at a trajectory that advances towards the target in small increments, allowing the fire support team to maintain control over the situation and make precise adjustments as necessary. This approach minimizes the risk of overshooting and hitting friendly forces, which is critical in combat scenarios where units may be closely coordinated.

Utilizing creeping fire, the fire support team can ensure that suppressive or destructive fire is effective against the enemy without jeopardizing the safety of allied troops engaged in the battle. This technique is particularly advantageous in situations where the risk of collateral damage is high and requires thorough coordination among units on the ground.
