What type of reconnaissance focuses on a specific route and terrain that influences movement?

The type of reconnaissance that focuses specifically on identifying details about a route and the terrain that impacts movement is Route Recon. This form of reconnaissance is integral in military operations as it provides critical information that helps in planning maneuvering and logistics. By assessing the route, troops can determine the best paths for travel, evaluate obstacles, and understand the terrain's characteristics that might affect mobility.

In contrast, Area Recon involves gathering information over a broader geographical area, without the focused intent on a specific route. Zone Recon covers a larger expanse as well, concentrating on understanding the overall environment within defined boundaries, which may or may not prioritize specific routes. Recon in Force is a proactive approach where forces engage the enemy and gather intelligence through active operations, rather than systematically assessing a route and the associated terrain. Thus, the focus on a specific route and its terrains is what makes Route Recon the correct answer in this context.
