Which of the following is NOT a request indicated by the codes provided?

The correct response indicates that a request for regular patrol is not among the designated code requests provided in the context of this question. In law enforcement communication, specific codes are often used to streamline operations and ensure that personnel can quickly understand and respond to requests. While codes exist for specialized units and equipment, such as air support or canine units, a request for a regular patrol typically does not require a coded request.

Regular patrols are a standard operation within law enforcement agencies and are usually conducted as part of ongoing duty assignments rather than as a response to specific requests. Therefore, the absence of a code for regular patrol reflects its routine nature and the expectation that officers are consistently on patrol. The other options refer to specialized units or resources that are deployed on an as-needed basis, making them relevant to the context of coded requests.
