What are the limitations of relying solely on air support for GCE missions?

Relying solely on air support for Ground Combat Element (GCE) missions comes with several limitations that can significantly impact mission success. While air support is a powerful tool, it is subject to various factors that can hinder its effectiveness.

One major limitation is the dependence on weather conditions; poor visibility or adverse weather can render air operations less effective or even impossible. Additionally, the concern of potential collateral damage is prevalent when conducting airstrikes, especially in populated areas. This can create ethical dilemmas and affect public perception, potentially complicating mission objectives.

Moreover, the effectiveness of air support can vary based on the specific tactical situation and the enemy's capabilities. Air assets might not always be available exactly when or where they are needed due to operational constraints or engagement rules, which can also impact their effectiveness.

Thus, choice B accurately captures these considerations, emphasizing that while air support is a critical component of modern military operations, it cannot be relied upon exclusively given these limitations.
