There are an additional 18 MiG-29 fighter jets of the Russian 102nd Military Base stationed in Gyumri. The Armenian anti-aircraft branch was equipped and organized as part of the military reform program of Lieutenant-General Norat Ter-Grigoryants. It consists of an anti-aircraft missile brigade and two regiments armed with 100 anti-aircraft complexes of various models and modifications, including the SA-8, Krug, S-75, S-125, SA-7, SA-10, SA-13, SA-16 and SA-18.
