What does the spotting term "Air" indicate?

The spotting term "Air" indicates that a round bursts in the air above the target, rather than impacting the ground. This type of burst is used to maximize the effectiveness of the explosion, particularly in situations where it is advantageous to have shrapnel or the effects of the blast spread over a wider area. The term essentially helps in communicating the specific nature of the fire to ensure that the observed impact aligns with tactical objectives. Understanding the function and purpose of airbursts is crucial for effective artillery placement and coordination in operations.
