Che? This blurb makes no sense at all...looks like a (bad) cut and paste from World of Tanks:
World of Warplanes is a team-based massively multiplayer online game dedicated to armored warfare in the mid-20th century. Based on military air dominance ranging from the 1930's through the 1950's, the game's advanced system of vehicle upgrade and development allows you to try out the vehicles and weapons featured in the game. Whether you prefer to exhaust your foes with fast and maneuverable light tanks, punch deep into enemy lines with all-purpose medium tanks, use the power of heavy tanks to eliminate opposing forces, or become a high-powered sniper using long-range artillery, each unit type is extremely lethal and effective when commanded by a true tank ace.
