Questions and answers
What type of weapon is the M240?
The M240 is a gas-operated, belt-fed, air-cooled, fully automatic weapon that fires from the open-bolt position. (paragraph 2-1)
What must Soldiers know about the M240 machine gun's components?
Soldiers must be familiar with these items and how they interact during operation. (paragraph 2-2)
What can thermal optics see?
Thermal devices see differences in heat. (paragraph 3-10)
What are the limitations of thermal optics around glass and water?
Water acts as a mirror and generally reflects IR, providing a false thermal scene. Glass acts similar to water, interfering with the sensors ability to accurately detect emitted radiation behind the glass. (paragraph 3-12)
How large is the weapons workspace?
The workspace is a spherical area, 12 to 18 inches in diameter centered on the Soldiers chin and approximately 12 inches in front of their chin. (paragraph 8-10)
