The M16A2 is classified as a lightweight, magazine-fed, gas-operated, air-cooled rifle, which highlights its design and functionality. Being lightweight contributes to the ease of handling and maneuverability for Marines during operations. The magazine-fed design enables quick reloading and sustained firepower, essential in combat situations. The gas-operated mechanism is notable for utilizing the gas produced from firing a round to cycle the action, allowing for semi-automatic and burst firing modes, which enhances the weapon's versatility. Additionally, the air-cooled feature means that the M16A2 does not require a cooling system like water-cooled models, making it simpler to maintain in the field.

The other options may include characteristics that do not accurately describe the M16A2. For instance, attributes like being heavy, belt-fed, or water-cooled would not apply, as the M16A2 is designed for portability and ease of use in various combat scenarios.
