What action should a squad take before moving to flank an enemy position?

Before moving to flank an enemy position, conducting a reconnaissance of the area is crucial. This action allows the squad to gather vital information about the enemy's strengths, weaknesses, and the terrain. By assessing the situation firsthand, the squad can identify potential obstacles, enemy locations, and other tactical elements that will affect their maneuver. This intelligence enables effective planning and execution of the flanking maneuver, as it ensures that the squad is aware of what to expect and can make informed decisions based on the current battlefield conditions.

On the other hand, while informing higher command is important for maintaining overall situational awareness, it does not provide the immediate tactical advantage that reconnaissance does. Waiting for artillery support might not be feasible or necessary, as it could lead to missed opportunities or delays in action. Forming a defensive line may be relevant in specific situations, but it is typically not a proactive step taken before a flanking maneuver; instead, the focus should be on movement and attacking the enemy from a different angle. Thus, reconnaissance stands out as the critical action to take before proceeding with the flank.
