A patrol rifle is typically characterized by its lightweight design, which allows for ease of carry and maneuverability in various scenarios. The term "cartridge fed" means that the rifle uses detachable magazines to supply ammunition, which is standard in most patrol rifle configurations. Additionally, patrol rifles are known for their versatility; they can be employed effectively in a wide range of law enforcement situations, from routine patrols to critical incidents.
The choice of "belt fed" does not accurately describe a typical patrol rifle. While belt-fed firearms are used in military and certain specialized law enforcement contexts, they are not standard for patrol rifles. Patrol rifles are predominantly magazine-fed for practicality, ensuring that officers can quickly reload and maintain operational readiness without the complications associated with belt-fed systems, which are bulkier and less maneuverable. Thus, identifying "belt fed" as the incorrect description accurately reflects the standard characteristics of patrol rifles used in law enforcement.
