What is one behavior indicated for repeating in training hand signals?

The correct answer emphasizes the importance of clarity in communication during hunting activities, particularly concerning safety. Hand signals are essential when hunting, especially in situations where verbal communication is not possible because of distance, noise, or the need for caution.

"Step back" as a behavior indicated for repeating in training hand signals ensures that all members of a hunting party are aware of the need to create space in potentially dangerous situations. Consistent reinforcement of the "step back" command encourages hunters to maintain a safe distance, thus reducing the risk of accidents, such as unintended discharges of firearms. Repetitive training on this signal establishes a shared understanding and can help reinforce situational awareness among hunters.

Other behaviors such as "cruising," "aggression," and "together" do not convey the same emphasis on safety or the need for clear and immediate action in a hunting context. While these behaviors might be relevant in other contexts, they do not reflect the critical safety practice illustrated by the repeated training on the hand signal to "step back."
