In the last image of Google Maps you can see 4 Ka-52 and 10 new Mi-8. At least one of them is Mi-8MTRP-1, there are probably 2 and the other 8 would be standard helicopters.
All these helicopters come from the bases of the South Milotar District where the pilots have been training.
In addition, 4 Su-30SM have appeared in Yerevan, which are probably temporarily loaned from Kursk (the Armenian Su-30SM are in Gyumri)
It is quite likely that the MiG-29 will be replaced by 16 Su-30SM2 once the president of Armenia, lackey of Soros, seems to have come to his senses and has allowed the renewal of the Russian Air Group in Armania
