USA
Armored vehicles and gun carriers manufactured and fielded by the United States of America and other North American nations such as Canada. Overall, tanks from the USA faction are exceptionally versatile, sacrificing the advantage of specialization in certain fields so as to perform adequately in any situation. Best suited as a multi-role combat tank for light, medium, and heavy tanks, but long-range to medium-range support for tank destroyers.
American vehicles tend to be more well-rounded then the other vehicles, making them the most versatile of all of the branches. For example, the German tanks have more accurate guns, fit for a sniper, Americans have accurate guns but they are not quite as accurate as the Germans by a minor margin.
The American Autoloader line at the low- to mid-tiers are scouting tanks with fast firing guns, high mobility and thin armor. The tier 7 T71 changed the play style as for the first time you get an autoloader. The tier 8 and 9 tanks again changed the play style as the tanks grew more sluggish, but with decent armor and devastating guns when used as second-line support. The T57 Heavy at tier 10 is a extremely dangerous tank with the capability to cripple a tier 10 tank with one magazine, while still able to bounce shots when hull-down.
To go into more detail the American Mediums play style is commonly referred as the "Jack of All Trades" Meaning you can play the roles of other nations, giving you the independence to do what you need on the battlefield. You shouldn't rely on one play style, not when you have the freedom to brawl, snipe, scout, assist... There is always something for one to do in one of these machines.
The American Heavies Don't give as much freedom as you'd expect from an American, to really get the full might of these tanks (From tier VII and above) you need to use hull down tactics Keep in mind that side-scraping and angling your armor (Exposing only your upper plate) around the side of a building work just as well.
The American TD's start out to be brilliant machines, with the fastest tracked vehicle of World War Two the M16 Hellcat at tier 6. Keep in mind that these quick and speedy tanks have cardboard armor and will get penetrated by high explosive ammunition. At tier 8 and above you will run into the "Land Yachts" or the T28 prototype and the T28 motorized gun carriages, these machines rely on their beastly guns and excellent frontal armor to savagely give beatings who are unlucky enough to be at the receiving end of your shells.
