More cold war assets

[upyr1]

With the Cold War Germany map, i think it's really imperative for ED to focus on filling in the missing cold war assets. Based on what modules we the primary  fovus should be on  things that left service after 1972 but entered service before 1991. 

The secondary focus should be assets that could do double duty for wwii maps. 

I think we need more Korean era modules before worrying about the ai assets.
