What type of reconnaissance patrol specifically aims to gather detailed information regarding all routes and obstacles in a defined sector?

The focus of the reconnaissance patrol in question is on gathering detailed information about all routes and obstacles within a defined sector, which is best addressed by the appropriate type of reconnaissance.

A zone reconnaissance patrol is specifically designed to obtain comprehensive information about a designated area, including terrain features, obstacles, and potential routes within that area. It typically encompasses a larger space than other reconnaissance types and aims to identify all factors that may affect operations, including enemy positions and movement options.

In contrast, other types of reconnaissance such as route, area, and point have more specific focuses. A route reconnaissance primarily looks at a single route for travel and identifies potential threats or obstructions along that path. Area reconnaissance gathers information on a specified area but may not delve into critical details about every route and obstacle. A point reconnaissance concentrates on a specific location, which does not align with the broader objective of understanding all routes and obstacles in a sector.

Thus, the zone reconnaissance patrol's comprehensive approach makes it the most suitable choice for the goal of gathering detailed intel on routes and obstacles in a defined sector.
