Use the latest Top of the Tree special and get to know a Tech Tree branch of true boy scouts. The American light tanks are well known for their mobility, good view ranges, and decent rates of fire. They are a great choice for aggressive reconnaissance work and supportive gameplay.
The top of the line is occupied by an eagle scout named after a famous cavalry officer, Philip Sheridan, who fought during the American Civil War. The 
X 
XM551 Sheridan was designed to cross rivers, be parachuted out of airplanes, and was even capable of firing anti-tank missiles with its unique 152 mm Gun-Launcher.
Just like its predecessors in this line, the Sheridan is fairly large for a light tank, but can rely on its outstanding view range. Use its mobility to anticipate enemy movements, stop their advances, and support teammates in need. The option to choose between two different gun types, a 105 mm Lightweight Gun and the aforementioned 152 mm boomstick, means you can adjust this light tank to your preferred playstyle. Whether you scout the fields with the best DPM of all Tier X light tanks, or use HEAT shells with 152 mm penetration to support your medium tanks with 700 alpha damage, you will always be prepared for a fight—scouts honor!
Make your way up the Tech Tree branch from April 5 at 07:00 CEST through May 5 at 07:00 CEST (UTC+2) and take advantage of great discounts and missions all the way to the top. Don’t forget that you can also purchase an extra boost if you want to speed things up!
