Which of the following is NOT an example of an intermediate weapon?

The option identified as not being an intermediate weapon is appropriate based on the definitions and classifications of weapon types used in law enforcement and military contexts. Intermediate weapons are generally defined as tools designed to incapacitate a suspect without causing fatal injury. They fall between verbal commands and lethal force, allowing officers to address threats with varying levels of intensity.

The expandable baton, non-lethal munitions, and physical restraints are all classified as intermediate weapons because they serve to control and subdue individuals in a manner that aims to minimize harm. Expandable batons can be used for striking or blocking, non-lethal munitions can incapacitate targets through various non-lethal means, and physical restraints are directly intended to limit a person's movement safely.

Pepper spray, while often considered a less-than-lethal option and used for defensive purposes, falls more into the category of a chemical agent rather than a weapon designed for intermediate force applications. Its primary role is to incapacitate through irritation and pain, but it does not function as a traditional weapon like the others mentioned, which typically involve physical restraint or impact. Hence, identifying pepper spray as the choice that does not fit the intermediate weapon classification aligns with the definitions commonly used in law enforcement training.
