An export version of the 3BM - 15 without the tungsten carbide plug . 3VBM9 / 3BM22 / 23 . Entered service 1976 . Tungsten carbide penetrator core sheathed in steel . 3VBM10 / 3BM29 / 30 . Entered service 1982 . Depleted Uranium - nickel - iron alloy sheathed in steel . 3VBM11 / 3BM26 / 27 . Entered service 1983 . Tungsten - nickel - iron alloy core sheathed in steel . 3VBM13 / 3BM32 / 33 . Entered service in 1985 . The projectile is a depleted uranium - nickel - zinc alloy , sheathed in steel . 3VBM17 / 3BM42 ( 3BM44 ) . Entered service in 1986 . The projectile is a tungsten alloy core sheathed in steel . 3VBM19 / 3BM42M ( 3BM44M ) . Entered service in 1994 Utilising an improved penetrator and a new Sabot . Reported to be tungsten alloy . 3VBM ? ? / 3BM46 ( 3BM48 " Svinets " ) . Entered service in 1991 Utilising a new Sabot . Reported to be Uranium alloy . 3VBM ? ? / 3BM46 ( 3BM48 " Свинец - 2 " ) . Entered service : Unknown . Utilising a new Sabot . Reported to be tungsten alloy . HEAT - FS . High - explosive anti - tank fin stabilised or HEAT - FS rounds . Typically used against lighter or older tanks and Armoured personnel carrier s . 3VBK7 / 3BK12 . Entered service 1962 . 3BK12M . Entered service 1968 . Uses improved 3V - 15 detonator . 3VBK10 / 3BK14 . Entered service 1968 . 3BK14M . Improved version , replacing steel liner with a copper liner . 3VBK16 / 3BK18 . Entered service estimated 1975 . 3BK18M . Improved warhead . Entered service estimated 1978 . Introduces wave shaping booster . 3VBK17 / 3BK21 . Entered service estimated 1980 . Enhancements to improve reliability of the copper jet formation . 3BK21B . Entered service estimated 1982 . Depleted uranium Liner to enhance penetration of advanced composite armours like Chobham . 3VBK21 / 3BK25 . Entered service estimated 1985 . 3VBK25 / 3BK29 . Entered service estimated 1988 . An experimental HEAT round that is obviously in close relationship with 3BK29 was displayed on VTTV - 97 exhibition in Omsk . Its cutaway shows a very complex and ingenious design , including shaped - charge precursor , the channel through the middle charge to allow passage of the rear jet and so on . The round is credited with 800mm RHA penetration which was illustrated by a picture of a 800mm penetration route . The picture shows that designers probably deliberately misaligned the charges so that the middle jet doesn ' t need to penetrate the core of the rear one . If the color of the liner is the same as that on the real round , it indicates that it is not copper , and therefore may have a significantly improved performance against ceramic armors . 3VBK27 ? / 3BK29M . First seen publicly in 1998 . Reportedly a triple charge warhead . HE - FRAG - FS . High Explosive Fragmentation Fin Stabilised . General purpose rounds , for use against infantry , bunker s and light vehicles and other ' soft ' targets . 3VOF22 / 3OF19 . Entered service in 1962 . Uses the 3V - 21 detonator ( mass = 0 . 431 kg , reliability = 0 . 98 ) . The 90 % lethal zone for infantry is reported to be 40 m wide and 20 m deep . 3VOF36 / 3OF26 . Entered service in 1970 . Uses the 3V - 21 detonator ( mass = 0 . 431 kg , reliability = 0 . 98 ) . The projectile creates between 600 and 2 , 000 fragments . ATGW / ATGM . 9M112 Kobra . The 9K112 Kobra ( NATO reporting name is AT - 8 Songster ) is also fired from the 125 mm main guns of the T - 64 and T - 80 series of tanks . 9M119 Refleks . The 9M119 Svir and 9M119M Refleks ( NATO reporting name : AT - 11 Sniper ) anti - tank guided missile has semi - automatic laser beam - riding guidance and a tandem hollow - charge HEAT warhead . It has an effective range of 75 m to 5000 m , and takes 17 . 6 seconds to reach maximum range . Refleks can penetrate about of steel armour and can also engage low - flying air targets such as helicopter s .
