from FAS

T-62A: Besides the standard 7.62-mm PKT coaxial machine gun with a range of 1,000 meters, the T-62A version features a 12.7-mm DShK antiaircraft machine gun with a range of 1,500 meters against ground targets and a slant range of 1,000 meters against aircraft. The T-62A also has a stabilized main gun, which enables the gunner to track and fire on the move with significantly improved accuracy.

T-62K: Command tank models also have a land navigation system which includes a gyroscopic compass and a calculator giving continuous enroute readout of the tank's location (in relation to its point of origin) and its distance from and azimuth to a predetermined objective.

T-62M adds protection, FCS and ATGM capability.

T-62 variants with a V-46 T-72-type engine add -1 to their designation.

T-62M1: Variant with Volna FCS but no missile launch capability.

T-62D: Variant with the Drozd APS vs ERA.

T-62MK: Command variant.

T-62MV: Version with ERA in place of the bra armor. The ERA includes Kontakt ERA and Kontakt-5 2nd-Generation ERA.

From wikipedia

T-62 - early production version, had a 14.5 mm KPVT machine gun in coaxial mount instead of the more common SGMT 7.62 mm.

T-62A - Added 12.7 mm anti-aircraft machine gun (which is often removed in the field) and changed coaxial machine gun to PKMT 7.62 mm. Also added was a stabalized main gun which let the gunner fire while moving with significantly improved accuracy. Though still when firing ATGMs from the gun it would need to make a quick stop. All T-62s in Soviet service were converted to these specifications before 1970.

T-62K - Command tank with additional communications gear, recognizable by multiple radio antennas instead of just one.

T-62M - added laser range-finder, reactive armour.

T-62D - added 9K118 Sheksna laser-guided antitank missile system (AT-12 Swinger), which is fired through the gun tube.

T-62MV - T-62D produced for export, most of which were given to North Korea and Syria as military aid.

T-62 This is the basic T-62 model, which essentially was a stretched T-55 chassis, with a new suspension, and a new turret equipped with the U-5T (2A20) Rapira 115-mm smoothbore gun. The gun has the new Meteor two-axis stabilization system.

T-62K This is the command tank variant of the T-62, and like earlier types, has one additional R-122 radio, a TNA-2 navigation system, a 4-meter antenna, but less ammunition. The corresponding command tank for the T-62M is the T-62MK.

T-62M (Also called T-62A) This tank includes the addition of a 12.7-mm antiaircraft DShK machine-gun on the loader's hatch. This modification included modification of the turret right side.

T-62M Model 1975 This is the T-62M with the addition of the KTD-1 laser rangefinder over the main gun mantlet.

T-62E The war in Afghanistan forced the Soviets to up-armor their tanks to provide better protection from infantry antitank weapons, such as the RPG-7. This upgrade led to the BDD appliqu? armor package. This package consists of a panel of armor on the glacis plate, two panels of "horse-shoe" armor around the front of the turret, and an optional package of belly armor for anti-mine protection. The total package adds 3.9 tons to the weight of the vehicle.

T-62M1 This further modification of the T-62A includes much of the modifications added to the T-55 to make the T-55AM2PB. These improvements include the Volna fire control system with the BV-62 computer, Meteor M1 gun stabilization package, TShSM-41U sight, KDT-2 laser rangefinder and 1K13 guidance sight package. This tank is equipped with the AT-12 Sheksna laser-guided antitank guided missile, which operates in much the same way as the AT-10 STABBER ATGM. This tank also includes the uprated V-55U engine, and the R-173 radio system. This vehicle is also usually fitted with the BDD appliqu? armor package.

T-62MV This is the T-62M fitted with the ERA package found on the T-55MV.

This seems to fit most closely with SPMBT. Although not completly. Well, then it seems that SPMBTs T-62 designations are modeled on Russian sources and not the messy contradictory western variations. I'm impressed
