The Armenian Army is the most efficient one in the post-soviet space, said Secretary Nikolay Bordyuzha, the Secretary General of the Collective security Treaty Organization (CSTO). "I was present at many exercises and saw the Armenian units, which are not numerous but well trained and rallied by a high moral spirit," said he. "Armenia's representatives in the CSTO are active and advance plenty of various offers and initiatives," Bordyuzha said, report Russian media.
