East Germany (DDR) in the Cold War - 1989 (Ground Forces Air Defense)

Ground troops - Nationales Volks Armee (NVA)
(National Peoples Army)

The Ground troops are divided East Germany into two military districts. This can cause confusion because the ground troops have the 3rd Military district (South) and the air defence troops had the 3rd Air Defense Division (North). The other one was the 5th Military District (North), which is less confusing vs. the 1st Air Defence Division (South).
I placed the Divisions in fictive assembly area's.

Details about the equipment can be found here:

All the NVA divisions are placed in assembly areas with Air defence employed to protect them.

GDR Reserves
Note: The GDR had five reserve Motorized Rifle Divisions. Mobilization was so effective that all five divisions could be combat ready within two days. These Division did not have SAMs like the SA-6/8 but only a S-60 (57mm) AAA regiment as cover.

The mobilization divisions were much lighter, especially in air defense. They had only a few MANPADS and lacked the ZSU-23-4 and the SA-13. As overall cover they were equipped with S-60 AAA. Only the 20th MRD appears to have operated SA-6 SAMs. Maybe it was a typo in the single source or real?
