Two main 'leaders' of the 'shared neighborhood' in term of military expenditures are fist Georgia and second Armenia.
Armenia has increased by more than 10% its defense budget, from 3,6% in 2000 to 4,5% in 2015. This soft jump does not however frame properly the reality of Armenian defense since Yerevan is tied to Moscow for military and defense assistance, and hosts a Russian base on its soil.
