What is the primary purpose of machine guns in infantry operations?

The primary purpose of machine guns in infantry operations is to provide sustained fire support to suppress or eliminate enemy forces. This capability is crucial for infantry units as it allows them to maintain fire superiority on the battlefield. Machine guns are designed to deliver a high volume of fire over an extended period, enabling them to keep enemy forces at bay, disrupt their movements, and reduce their ability to effectively return fire. By laying down continuous fire, machine guns play a vital role in force protection, support for maneuvering units, and the overall execution of tactics aimed at neutralizing threats.

Additionally, while machine guns can potentially play a role in various capacities on the battlefield, their primary function remains focused on direct fire engagements and strategic support rather than roles like sniper support or training. This distinctive function emphasizes their integral value in combined arms operations.
