The objective of an ambush is to?

The objective of an ambush is primarily to reduce enemy effectiveness and capture supplies. An ambush is a surprise attack carried out by combatants positioned to catch the enemy off guard. The intent is to inflict maximum damage on the enemy while minimizing the risk to the ambushers. By targeting enemy forces in a surprise attack, the ambushers can disrupt enemy operations, degrade their combat capabilities, and seize valuable resources or supplies. This tactical approach leverages the element of surprise, allowing the ambushing unit to inflict harm before the enemy can effectively respond or regroup.

While securing territory, providing reconnaissance, and conducting a full assault are important military objectives, they don't directly align with the primary strategic intent of an ambush. Securing territory typically requires sustained efforts and holding positions, reconnaissance focuses on gathering intelligence rather than attacking, and a full assault implies a more direct and ongoing confrontation rather than a quick, deliberate strike typical of an ambush.
