Which technique is recommended for responsive fires when the observer is experienced?

The recommended technique for responsive fires when the observer is experienced is hasty bracketing. This method allows for a quick adjustment of fire based on the observer's initial assessment and experience with the target environment. Hasty bracketing involves firing rounds to establish a range or lateral deviation from the target quickly, enabling the observer to refine the target's location effectively without extensive delay.

An experienced observer can rapidly evaluate the impact of the initial rounds and make informed corrections to achieve an accurate strike. This technique is particularly useful in dynamic situations where speed is critical, and the target may not remain stationary or identifiable for long.

Other techniques may not offer the same level of efficiency and responsiveness as hasty bracketing. While creeping fire, one round adjustment, and successive bracketing can be effective in their contexts, they may require more time or additional rounds to achieve desired accuracy, which may not be suitable for all operational scenarios where quick reactions are essential.
