What type of equipment is generally used routinely during patrols?

The type of equipment that is generally used routinely during patrols is classified as En Route equipment. This category encompasses the essential tools and gear that personnel utilize throughout the entirety of their patrolling missions. En Route equipment is necessary for maintaining operational readiness and effectiveness while moving from one location to another. This equipment often includes basic supplies such as communication devices, navigation instruments, first aid kits, and other essential gear that ensures the safety and efficiency of the patrol.

In contrast, Objective Area equipment is specifically utilized at the patrol’s destination and may not be relevant for the entire journey. Observation equipment is focused on gathering intelligence and requires a specific setup, usually employed at designated observation posts rather than throughout the patrol. Routine equipment may refer to standard gear but does not necessarily convey the comprehensive nature of En Route equipment. Therefore, En Route equipment stands out as the correct answer for routine patrol operations.
