An antitank gun is a type of weapon designed to destroy or disable tanks. There are several synonyms for an antitank gun, including tank buster, gun-howitzer, tank killer, anti-armor gun, and tank destroyer. These weapons are typically large-caliber artillery pieces that fire high-explosive shells capable of penetrating tank armor. Antitank guns are an essential component of a military's armored warfare strategy and can be used defensively to protect territory or offensively to assault enemy forces. The use of antitank guns has become increasingly important as tanks have become more sophisticated and technologically advanced, making them more difficult to destroy with conventional weapons.
