Heavy machine guns are powerful firearms designed to provide sustained fire in military operations. They typically use larger caliber ammunition, such as .50 BMG or 7.62mm, allowing them to penetrate armor and deliver significant firepower. These weapons are often mounted on vehicles, aircraft, or tripods for stability and accuracy. These guns are used by various military forces around the world, including the United States Armed Forces and NATO allies. Heavy machine guns can fire hundreds of rounds per minute, making them effective for suppressing enemy positions and providing cover for advancing troops.
