In a single-file line of three hunters, what is acceptable for the hunter in the middle to use?

The middle hunter in a single-file line of three hunters should use the cradle carry. This carry method is particularly useful for ensuring safety and maintaining control over the firearm, especially in close proximity to others. In the cradle position, the hunter supports the firearm securely with both hands, which minimizes the risk of the muzzle pointing toward another person. This is crucial for safety, as it helps prevent accidental discharges that could occur if the muzzle were to break the plane of a fellow hunter.

Using the cradle carry allows the middle hunter to keep the firearm elevated and stable while still being mindful of the space and safety of those to the front and back. The other carry options, while functional in other contexts, may not provide the same level of security and control necessary in a closely packed situation, making the cradle carry the most appropriate choice for this scenario.
