The standard rate of fire is 200 rounds per minute, and has a range of 2,000 meters (depending on the ammunition used). A wide range of ammunition has been developed for this weapon, making it capable of defeating the majority of armored vehicles it is likely to encounter, up to and including some main battle tanks.
