Which of the following is NOT a type of baton carry?

The single-handed carry is recognized as a common method for carrying a baton. In this method, the officer holds the baton in one hand, allowing for quick access and maneuverability. This is especially advantageous in situations where the officer may need to use their other hand for various tasks or to maintain a firm grip on a primary weapon.

In contrast, the other options—vertical carry, two-handed carry, and outside arm carry—represent valid techniques employed in baton handling. Each of these methods serves specific purposes based on an officer's operational requirements, such as allowing the baton to be easily accessible while maintaining a posture that is conducive to readiness in various situations. Therefore, identifying the single-handed carry as not fitting into the standard categorized types of baton carry is a misunderstanding of the operational techniques utilized in baton handling.
