An assault rifle is a type of firearm designed for rapid fire and versatility. It typically uses an intermediate cartridge, allowing it to be effective at both short and medium ranges. These rifles are often used by military forces, law enforcement, and sometimes civilians. Popular examples include the AK-47 and the M16, which are known for their reliability and ease of use. Unlike traditional rifles, assault rifles can switch between semi-automatic and fully automatic firing modes. This means they can fire one bullet with each pull of the trigger or continue firing as long as the trigger is held down. Their design allows for quick reloading and adaptability in various combat situations.
