Which method of attack requires that the intended target or mark is tally/contact/captured by the aircrew?

The method of attack that requires the intended target to be visually identified by the aircrew is Bomb on Target (BOT). This approach necessitates that the aircrew maintain a direct line of sight to the target to ensure precision in the attack, allowing for adjustments based on the actual conditions on the ground, such as target displacement or changes in the environment.

In this method, visual confirmation plays a crucial role, as it enhances the accuracy of the strike and minimizes the risk of collateral damage. The aircrew's ability to see and confirm the target ensures that their ordnance is effectively employed directly against the intended mark.

Other methods like Bomb on Time (BOT), Bomb on Correlation (BOC), and Bomb on Coordinate (BOC) do not require visual confirmation. Instead, they rely on timing, correlation with a known point, or predetermined coordinates respectively, which may not guarantee that the weapon is delivered directly onto the target as accurately as in the case of Bomb on Target.
