An ambush of __________ is conducted when available information does not permit detailed planning before the patrol departs.

An ambush of opportunity is particularly relevant when a unit is deployed without the benefit of detailed intelligence or planning. This type of ambush relies on the element of surprise and the situational awareness of the patrol. The key characteristic of an ambush of opportunity is that it occurs in a spontaneous context, allowing troops to act swiftly in response to unexpected targets or situations that present themselves during their movement. This contrasts with other types of ambushes, which generally require more forethought and planning regarding location, timing, and enemy patterns.

By relying on opportunity, the patrol remains agile and can immediately exploit any situational advantages that arise, making this approach vital in fast-changing environments where preparation may not be feasible. This adaptability enhances the effectiveness of the ambush, as it capitalizes on the moment rather than waiting for a pre-planned scenario to unfold.
