What is the primary function of the M240B machine gun?

The primary function of the M240B machine gun is to perform as an automatic machine gun. This weapon is designed for sustained fire, allowing it to provide continuous round delivery against targets, which is essential during combat situations. The M240B is capable of engaging enemy personnel and equipment effectively, making it a critical asset on the battlefield.
