<h2>Armament</h2><p>82 mm B-10 recoilless gun; NORINCO 82 mm recoilless gun Type 65 and 65-1.</p><h2>Development</h2><p>The Soviet 82 mm B-10 smoothbore recoilless gun first appeared during the 1950s and is now rarely encountered other than, perhaps, with special forces. Some B-10 guns were exported to nations such as Egypt and Syria but most of them have now been withdrawn. The Chinese NORINCO concern, however, copied the basic B-10 design to produce the Type 65 and the later Type 65-1 which incorporates some slight alterations to lighten the carriage. For both Type 65 and Type 65-1 the ammunition remains the same. The Type 65-1 is apparently still in production and has been offered for export sales. Some have been exported to Pakistan and Tanzania . At one time 82 mm B-10 ammunition was manufactured in North Korea and Poland . The later NORINCO 82 mm Type 78 recoilless gun employs different ammunition (see following entry).</p><h2>Description</h2><p>The 82 mm B-10 recoilless gun rounds resemble mortar bombs and are produced in two forms, HEAT and FRAG-HE. There are two types of HEAT. One is the BK-881 and the other the BK-881M which has a slightly more powerful warhead. On both 82 mm HEAT rounds the pear-shaped body is made of cast steel with a long tubular boom threaded into the base. Around the base of the boom is placed the propellant charge in a manner similar to that used with mortar bombs but under the ring-shaped charge, which is held in position by two spoked rings, is a multiperforated steel disc through which the propellant gases are vented when the round is fired. The resultant muzzle velocity for the BK-881 is reported to be 322 m/s. The shaped warhead for the BK-881 contains 460 g of RDX. That for the BK-881M contains 550 g of RDX. The BK-881 is provided with a PIBD GK-2 while the BK-881M has a PIBD GK-2M. The BK-881M also has a slightly larger propelling charge. Both HEAT warheads are effective only up to combat ranges of about 400 m although the maximum possible range is greater. Up to 400 m both warheads can penetrate about 240 mm of armour under ideal conditions but accuracy can be affected by light side winds. The 82 mm O-881A FRAG-HE round follows the same general outline as the HEAT, with a fragmenting cast iron body containing 470 g of TNT and dinitronapthalene. Muzzle velocity is increased to 400 m/s and maximum range is a possible 4,500 m although effective combat ranges are much shorter. The nose fuze is a PD GK-2.</p><h2>Authorised fuzes</h2><p>HEAT - PD GK-2 or GK-2M FRAG-HE - PD GK-2 Equivalent rounds CHINA , PEOPLE'S REPUBLIC</p><p>CHINA</p><h2>Manufacturer</h2><p>China North Industries (NORINCO)</p><p>Type: HEAT, FRAG-HE</p><p>Description: Chinese 82 mm Type 65 rounds differ significantly from the Soviet original.
