87 mm artillery

The term "87 mm artillery" typically refers to artillery pieces that have a caliber of 87 millimeters. This size is somewhat unusual, as most artillery is categorized in larger standard calibers such as 75 mm, 105 mm, 155 mm, etc. One of the most notable examples of 87 mm artillery is the Soviet 87 mm anti-tank gun, which was developed during World War II.
