Soviet Machine Gun/Artillery Divisions-what were they?

[Vespers War]

I found an old UK manual from the mid-90s (the 1996 Army Field Manual, Volume II) that lists what they thought a Machine-Gun Artillery Division consisted of at the time. It's pretty defensive, with just enough armor for localized counter-attacks.

1 Recce Company (28 BMP-2, 6 BTR-80, 6 BRDM-3)
1 Engineer Battalion
1 Anti-Tank Battalion (12 MT-12 Rapira, 12 9P148 Konkurs, 17 BTR, 6 AGS-17, 6 2S3 Akatsiya)
1 Tank Regiment (95 T-72B, 65 BMP-2, 24 2S1 Gvozdika, 18 9K115 Metis, 4 2S6 Tunguska, 6 9K35 Strela)
1 Air Defense Regiment (30 9K331 Tor)
1 MLRS Regiment (54 BM-21 Grad)
1 Artillery Regiment (72 2S3 Akatsiya)
3 Machine-Gun Artillery Regiments

Each MGAR has:
4 MG Battalions (each with 3 MG companies and 1 special weapons group of 1 anti-tank company, 1 mortar battery, 1 grenade launcher platoon, and 1 air defense platoon)
1 Mechanized Battalion (1 tank company, 3 motorized rifle companies, and 1 special weapons group)
1 Self-Propelled Artillery Battalion of 3 batteries
1 Anti-Tank Battalion of 4 batteries, 2 of guns and 2 of self-propelled ATGMs
1 Air Defense Battalion of 3 self-propelled batteries
1 Engineer Company
3 Tank Companies each of 10 dug-in tanks
2 Artillery Battalions each of 3 dug-in batteries
1 Casemate Company with 18 prefabricated retractable turrets for machineguns, grenade launchers, or ATGMs
