What is a primary feature of the 240B machine gun?

The primary feature of the 240B machine gun being belt-fed, air-cooled, and a crew-served weapon is essential to its operation and role on the battlefield. Being belt-fed allows for a continuous supply of ammunition, enabling sustained fire over longer periods, which is crucial during combat situations. The air-cooled aspect means that the weapon does not require water to operate, making it more versatile and easier to transport than some water-cooled alternatives. Additionally, labeling it a crew-served weapon signifies that it is typically operated by a team rather than an individual, allowing for more efficient management of firepower and ammunition handling.

In contrast, the other statements describe aspects that do not accurately reflect the 240B's design and intended use. For example, while "recoil operated" and "handheld" may apply to some firearms, they do not characterize the 240B, which is significantly larger and intended for crew operation rather than individual use. Similarly, the terms "direct fire" and "gas operated" can describe other weapon systems but do not align with the defining characteristics of the 240B. Lastly, the descriptors "compact and lightweight" do not represent the 240B accurately, as it is designed for heavier support roles
