A reconnaissance patrol may consist of the following three elements: headquarters, security, and __________.

In a reconnaissance patrol, the inclusion of a reconnaissance element is essential for the mission's success. This element is primarily responsible for gathering information about the enemy, the terrain, and any other pertinent factors that could influence the operation. Their role is to observe, report, and provide intelligence to the headquarters, which guides decision-making.

The structure of a reconnaissance patrol typically involves three key components: headquarters for command and control, security to protect the patrol from detection and engagement by the enemy, and the reconnaissance element that performs the core function of scouting and intelligence gathering. This triad ensures a balanced approach to the mission, allowing for effective planning and execution.

In contrast, the other options fail to represent the standard components that directly relate to the specific roles within a reconnaissance patrol. While support might be valuable in other contexts, it doesn’t specifically describe an element involved in the reconnaissance function. Similarly, while assault might be relevant in offensive operations, it is not a defining element in the context of a patrol focused on reconnaissance. The point man serves a specialized role in leading the patrol, but is not one of the primary elements that constitute the patrol’s structure. Thus, the correct answer aligns perfectly with the defined elements of a reconnaissance patrol.
