After Russia presented its state-of-the-art Armata battle tank last year, Ukrainians ridiculed it on social media. "This is a coffin on treads," blogger Mikola Gritsenko wrote on Facebook. Ukraine plans to sell its rival tank, the BM Oplot, for $4.9 million to overseas clients. The price tag on an Armata is about $7.8 million, although no export customers have been lined up. The first exports are planned for 2020, according to Russia's Military Industrial Commission.
