The M4 carbine was considered easier to use than the M16 in urban fighting during the Iraq War primarily due to its compact size and portability. While the M16 measures approximately 100 cm (39 inches) in length, the M4 is a shorter, lighter carbine version of the same platform. With its stock retracted, the M4 measures only about 76 cm (30 inches), making it significantly more maneuverable in the close quarters characteristic of urban combat environments.12
