The -80 was the banner tank project under Ustinov because the Marshall wanted turbines. T-72B were introduced in 1984-85 but initially they were assigned to Units in the Soviet Union, usually replacing T-55/54, T-72B were reported by USAEUR and CIA in the CGSF (not GSFG). By 1989 (when the CFE numbers were finalized) there was a total of 3,020 T-80B and BV in Germany.
According to Zaloga's "Tank War - Central Front NATO vs. Warsaw Pact" (Osprey, 1989), the T-72 was not widely used in East Germany (being the most common type in western Soviet military districts, nonetheless), but it doesn't say the type was not used at all. It also says that the predominant version of the T-72 in service with the Soviet Groups of Forces in Central Europe was the T-72M1.
The T-72M1 is the equivalent of Data Card SM-2B: T-72AV.
Nevertheless, being MBT a hypothetical conflict wargame, I don't see the point of not including T-72s to the set. It adds.
As stated previously, force compositions are subject to question. For example, the 4th Battalion, 8th Cavalry; 3rd Battalion, 64th Armor; and 2nd Battalion, 66th Armor all competed in the CAT 1987 (Canadian Army Trophy) competition in June of 1987 with M1IP Abrams, not M1A1 Abrams as listed here.
Thanks Jim! I'm in the process of confirming and updating the OOB right now with information from veterans that served in those units now.
At least for 3-64AR, 3rd ID this is one of the responses: "The only units in 3ID that ever had IPs were A/3-64 and A/2-64 from July '86 through June '87, for the '87 CAT Competition. The Division transitioned from base M1 to M1A1 in 1987, with 1-64 being the first to switch over. 3-64 was last, in July, once CAT was over."
Haven't gotten around to asking about 2-66AR, 2nd AD FWD, or 1st ID FWD yet.
I'd like to add to this thread that the only official OOBs for the MBT game will be the ones included in the MBT Playbook. Everything posted here must be considered either as "alternative" or "variant", not official, so these posts cannot be treated neither as "corrections" nor "accurate" force lists. In addition, remember that MBT is a hypothetical game set in one possible version of 1987 and is not intended to be the sole representation of that period in time.
There are updated wire-diagram OoBs for 1989 NATO forces on Wikipedia that look pretty solid. If you look up NORTHAG and CENTAG you'll find links for every Corps that was present. Looking up GSFG will do the same for the Soviets. Less sure on where to get other WP nations' OoBs for that period, however (e.g. the East Germans, Poles, etc.)
