NATO Supreme Allied Commander General Curtis Scaparrotti said that the Russian military is modernizing with impressive results and its senior officers have displayed flexible thinking in their strategic doctrine.
"You can see that they've imposed discipline on their force, they are pretty agile in thinking. Russia is back… I'm impressed," Scaparrotti noted.
According to him, the Russian armed forces demonstrated the high level of their military capabilities particularly during Russian military operation in Syria.
"They are modernizing… We have an adversary here that we have to take very seriously, in my opinion," Scaparrotti stressed.
