What does two tugs represent in the OATH method of signaling on a search line?

In the OATH method of signaling on a search line, two tugs specifically indicate that the team should advance. This system is designed to facilitate clear and efficient communication between firefighters in low-visibility or hazardous environments, such as during a search and rescue operation. The number of tugs corresponds to different commands, making it easier for team members to understand when to proceed further into the area being searched.

The concept of signaling through tugs is critical in ensuring that all team members are synchronized in their actions, which helps in maintaining safety and effectiveness during operations. When a team member feels it is safe and appropriate to make progress, they will use this specific signal to prompt others to move forward.
