What is a common action upon contact during a patrol mission?

Establishing a defensive position is a crucial action upon contact during a patrol mission because it allows soldiers to effectively respond to the threat while maintaining control of the situation. When contact is made, the immediate focus is on protecting the squad or unit from further attack. Setting up a defensive position enables the unit to leverage cover and concealment, providing a tactical advantage against the enemy. This action also facilitates coordination, allowing team members to assess the situation, distribute responsibilities for defense, and prepare for potential follow-up actions, such as calling for reinforcements or engaging the enemy.

In contrast, retreating immediately without properly assessing the situation can lead to disorder and increase vulnerability to enemy fire. Communicating with the command center is essential, but it usually follows the immediate action of establishing a defensive posture to ensure that the unit can maintain its operational capability. Ignoring the contact and proceeding can result in severe consequences, as it disregards the immediate threat to the unit's safety and mission effectiveness.
