Which aspect is a significant limitation of close air support in military operations?

Identification of targets is a significant limitation of close air support in military operations because it requires precise coordination between ground forces and air assets to ensure that the right targets are engaged. Misidentification can lead to collateral damage, friendly fire incidents, and a potential loss of trust between the supporting air units and the ground troops. This limitation is exacerbated in complex environments where enemy forces may blend in with civilians or use tactics to disguise themselves as non-combatants. Effective target identification is critical not only for the success of the air mission but also for the safety of the personnel involved in ground operations. Ensuring accurate identification helps to maintain operational effectiveness and minimizes unintended consequences during military engagements.
