Thanks Pat, I can see the extensive work you did in your Patch thread. I don't know how you keep up with developments in so many nations, I have difficulty with just segments of one!
Re: M60A1(RISE/Passive), per History of the Shillelagh Missile System 1958-1982 by DeLong, Barnhart and Cogle: in February 1978 DA decided to phase down the M551 and replace it with the RISE/Passive with new ammo. The swapout began with 11ACR from June 1978, 2ACR was reequipped from September, then USAREUR DIVCAV units from December 1978 through March 1979. CONUS based cav units received RISE/Passives from April 1979, completing the Sheridan swapouts in all cav units during FY80 (I found no reference to 2ID Sheridans being swapped out with RISE/Passives, so they probably received M48A5s instead).
I had thought most M60A2 battalions were reequipped with M60A1s, but production rates and known phaseout dates seem to indicate that at least some of the six battalions in USAREUR received M60A3s instead. Per History of the Shillelagh Missile System:
Reduction in force ordered by DA April 1979
1/32AR, 3AD - 5/79 (received all 54 M60A3s at once)
2/68AR, 8ID(M) - 6/79 to 8/79
2/64AR, 3ID(M) - 9/79 to 11/79
3/33AR, 3AD - 1/80 to 3/80 (had catastrophic gun breech failure July 1979)
Was originally planned to leave two battalions in USAREUR until 1987, but decision to phase out the M60A2 was made February 1980, accelerated phaseout ordered May 1980
1/37AR, 1AD - 6?/80 to 8?/80
3/64AR, 3ID(M) - 9?/80 to 11?/80
The last two above may have received 11ACR's M60A1(RISE/Passive) pending availability of M60A3(TTS) for 1/37AR, M1 for 3/64AR. Phaseout of M60A2 completed during FY81, which leaves the one battalion at Fort Hood being the last, probably during spring 1981, most likely with rebuilt M60A1(RISE/Passive).
By December 1979, M60A3(TTS) appear to have been test-fielded by 1/10CAV, 4BDE 4ID(M); after a six month evaluation, 11ACR began to be reequipped from July 1980, a mere two years after receiving M60A1(RISE/Passive). 3/8CAV, 8ID(M) was apparently next, in December. In the first five months of 1981, four regular tank battalions appear to have received the TTS, I am not sure which division but I'm leaning toward 3AD, followed by 2ACR starting in June. Three more DIVCAVs received TTS before all six tank battalions of 1AD were reequipped from February to November 1982. Four remaining battalions of 8ID(M) appear to be reequipped from December 1982 to May 1983, with 3BDE 1ID(M) aka 1ID(FWD) being one of the last USAREUR units reequipped by July 1983 (the latter per
www.usarmygermany.com). TTS fielding to CONUS must have begun at this point, with 2ID in Korea receiving theirs by mid 1985. Per REFORGER 1986-1993 by Tankograd, the latest photo evidence of M60A1(RISE/Passive) use by active duty units was by 1BDE, 1ID(M) during REFORGER 86.
While this has been culled from multiple sources, some of the dates and units are educated guesses, so if you have more definitive info then please let me know, thanks
