What is a key disadvantage of using the M240 in close quarters?

The key disadvantage of using the M240 in close quarters is that its firepower and weight can make it less maneuverable. The M240 is a heavy machine gun, which provides significant firepower; however, this weight can hinder quick movement and responsiveness in tight spaces. In close quarters combat, where agility is crucial, the bulk and heft of the weapon can prevent operators from effectively navigating the environment and responding to threats rapidly. This can become a critical limitation, as engaging in close quarters often demands quick positioning and the ability to quickly switch between targets. The design of the M240, optimized for open field engagements, does not align well with the quick-handling requirements typical in close-quarters scenarios.
