The B-10 is a recoilless rifle of Soviet origin. It was developed in the early 1950's to replace the earlier SPG-82 rocket launcher in Soviet service. The B-10 was produced in large numbers for use with Soviet forces and their allies. Although it was soon inadequate against Western armor the B-10 remained in use with many third world nations as a cheap an effective infantry support weapon.

The B-10 is a recoilless rifle of a rather conventional design. It is a smoothbore weapon that is loaded from the rear, through a breech that swivels sideways. A basic optical sight is fitted on the left side of the weapon. The B-10 is fired from a collapsible tripod. An axle with two wheels is attached to the base of the tripod when in transit. Two grips near the muzzle are used to pull the weapon. At least two people are required to operate the weapon effectively.

The B-10 fires mortar-like projectiles at a rate of fire of 6 to 7 rounds per minute. High explosive rounds are used against infantry and HEAT rounds against vehicles. The original and most common HEAT rounds pierce 240mm RHA. The Chinese developed more effective rounds that may pierce over 350mm RHA. The effective ant-tank range is 400 meters. The effective range of high explosive rounds is over 1 km, but may reach as far as 4.5 km.

The B-10 can easily be pulled by hand over short distances. Over long distances it is to be moved by vehicle. Soviet forces often employed the B-10 from the BTR-50 armored personnel carrier. In many third world countries the B-10 has been fitted on a variety of jeeps and pickup trucks.

The B-10 was widely employed with the Soviet forces since the mid 1950's until it was fully replaced in the 1970's. The B-10 was widely exported and used during most conflicts in the Middle East, Africa and Asia. China was also one of the main producers and users of this weapon. Nowadays the B-10 is considered obsolete but remains operational in limited numbers today, mostly with third world nations.
