Chaffee
Slinking back down to Tier 5 and visiting the United States tech tree, we have the Chaffee, a Light tank that belongs to one of the best USA tank lines in World of Tanks. The Chaffee offers itself as a scout or a flanker, but one must first know when to flank.
Part of its appeal is its handling. Its manoeuvrability lends itself to harassing enemy tanks and then retreating behind cover, and repeating. Its speed, like the PzIC, is what makes the Chaffee such a fun tank to pilot, that and its accurate, and rapid-firing, guns. A tricky pilot can zoom behind enemy lines and harass TDs and SPGs with ease, punishing them for not paying attention.
