Most KOBRA armed tanks are using the wrong missile.
Normally when you move from a CatC ATGM carrier such as M2 Bradley with TOW we logically expect the CatB M2A1 to carry a better missile such as I-TOW (actually it should be TOW-2 but thats another post..), and largely, in 99% of cases this is the norm. This is in fact so common as to almost be considered the rule except that....... Unfortunately in the case of MBTs such as the T-64 and T-80 series, the vehicles move from CatC-CatA, getting progressively more expensive while continuing to pay a premium for an increasingly obsolete missile. This stems from an erroneous assumption that there are only two missiles in the KOBRA family, the 9M112 "Kobra" and the 9M128 "AGONA". This assumption is erroneous because cursory research has turned up at least two, if not three "KOBRA" variants, 9M112 and 9M112M, (9M112M2). This wouldn't really be a problem except for the fact that 9M112 "KOBRA" is a decidedly CatC missile that keeps ending up on CatA MBTs, Its like the M2A2 being forced to carry around TOW instead of TOW-2.
Wikipedia seems to be relatively spot on as far as variants go although nomenclature varies from source to source, nomenclature and system assignment data displayed on the wiki page correlates with that of independent sources on the web. The actual penetration is anyone's guess and any values are placeholders, i'm going to rely on Eugen to figure out what is best for 9M112M and 9M112M2. CTH for the 9M112 family has been raised to 50%, it is guided by a highly advanced, integrated FCS that combines everything from LRF to meteorological sensors. Of course looking at these one has to wonder if SVIR might need a 5% accuracy bump... being a laser guided system..... but that's a different post.
An illustrative explanation.... In French for relevant persons....

Firstly, accuracy values provided for the KOBRA family of missiles (apart from AGONA) are derisively low, the system has a CTH conservatively estimated as .8 against a moving tank sized target at 4000m, this is definitely worth at least 50% acc for base variants. The missile's slow speed and high number of hit rolls, not to mention low ammo count an RoF will continue to limit its utility, and ability to be a long range menace. I will also take the time to address the abominable treatment of the T-64B/BM gun as well, this is relevant because it will illustrate why "KOBRA" should not have the abominable accuracy it currently has been assigned.
For our purposes the variants we are concerned with are:
9M112 basic version of the missile entered service in 1976 as part of the missile system 9K112 T 64B;
9M112M changes improved tested in 1977 and adopted in 1978 as part of the missile system 9K112 1 in the T 80B, armor penetration increased by 20%. Production started in 1979;
9M112M2 variant 9M112 with armor penetration increased by 40% compared to the original model, testing began in 1983. The dimensions of the missile and the operating conditions remained unchanged.
The tanks will be addressed on a case by case basis:
As far as the missile is concerned the T-64B has sort of the right missile. The T-64B was equipped with the 9K112 armament system firing the 9M112 missile which we know in game as "KOBRA", according to some sources the 9M112 had only a limited production run and was superseded by the 9M112-1 for use on the T-64B.
The fire control complex of the T-64B is the 1A33:
Thus the absurdity of it being assigned the 2100m range customarily assigned to coincidence rangefinder equipped tanks quickly becomes apparent. It is a tank with a high caliber, high velocity smoothbore main gun controlled by a digital FCS with integrated LRF and meteorological suit in addition to dual plane stabilization, most other tanks with the same FCS+armament characteristics get 2275m.The fire-control system is designated the 1A33 and enables the T-64B to engage stationary and moving targets while the vehicle itself is stationary or moving. The fire-control system includes the two-axis stabilised IG42 laser range-finder sight, the 1V517tank ballistic computer with data inputs being automatic (from the range-finder or manual), the 2Eh36M armament stabiliser, the IG43 fire-control panel and some other elements..... such as a a 1B11 cross-wind sensor
The T-80B is using the wrong missile. Why? Because the 9K112 armament system of the T-64B was updated to a new variant for T-80B called 9K112-1 with a completely new missile variant designed for the T-80B, designated 9M112M, This missile was developed and in production by 1979 (Pre CatC) and quickly backfitted to T-64B's, replacing the 9M112 (likely the source of the confusing 9M112-1 designation). The T-80B should thus be carrying the 9M112M, a missile supposedly possessing 20% more penetrative power than that fixed to the 9M112 "Kobra".
Same FCS story as T-64B, Absolutely ZERO reason for this tank to be burdened with 2100m range, it even has a damn crosswind sensor in addition to a LRF, digital FCS, multi-axis stabilization.... need we go on? Oh right!! The missile! This tank has an intro date of 1983, meaning it is able to take advantage of either the 9M112M or 9M112M2 missiles. Testing of the 9M112M2 missile was begune in 1983, resulting in a missile with armor penetration increased by 40% compared to the original model. That being said I believe that missile should be reserved for the T-80BV, the result being that the T-64BM is therefore assigned 9M112M, and needs no change in price.
This is a CatA MBT, yet it is still carrying the 9M112, the Soviet equivilant of TOW or Shillelagh-A.... Obviously the tank needs a much better missile, seeing as Eugen is understandably skittish about giving the 9M128 to T-80BV, a perfectly viable compromise is to choose a further incremental development of the 9M112 family, that missile of course is 9M112M2 the testing of which again began in 1983 (the only differences being minor, constituting a different warhead, no changes to guidance).
