War Thunder’s United States ground forces tech tree represents one of the most diverse and historically significant progression systems in the game, offering players a journey from the hastily prepared defenses of early 1941 to the overwhelming industrial might of 1945. This line of vehicles spans the evolution of American armored doctrine, showcasing a shift from fragile improvised solutions to purpose-built machines of war. Understanding the structure and nuances of the USA tank tree is essential for any player seeking to master the complexities of combined arms warfare in the game.
The Foundation: Early War Struggles and Necessity
The upper branches of the USA tree begin with the fundamental challenges faced by the American military before and during the early months of World War II. Players will encounter vehicles like the M2 Light Tank, which, while mechanically reliable, was under-gunned and under-armored compared to contemporary European designs. These initial machines serve as a crucial tutorial, teaching players the basics of mobility, positioning, and map awareness. The progression through this early segment highlights the painful lessons learned by the US Army, forcing a rapid adaptation to the realities of modern conflict.
The Medium Tank Revolution: Lee to Grant
A pivotal moment in the tree is the introduction of the M3 Lee and its successor, the M4 Grant. These medium tanks, distinguished by their unique multi-turret configurations, provided the firepower and durability necessary for the North African campaign. The M3 Lee, with its prominent commander’s cupola, was a stopgap design rushed into production, while the M4 Grant refined this concept with improved armor layout and a more efficient powertrain. Mastering these platforms teaches players the importance of volume of fire and the tactical flexibility offered by hull-down positions.
The M4 Sherman: The Backbone of the Force
The M4 Sherman family forms the absolute core of the American mid-to-late war experience, and for good reason. This line of medium tanks is the workhorse of the US arsenal, defined by reliability, ease of production, and constant incremental improvement. Players will guide the Sherman through numerous variants, from the initial M4 (76) to the specialized M4A3E8 “Easy Eight.” The tree branches significantly here, presenting choices between high-velocity 76mm guns for anti-tank roles and larger 105mm howitzers for infantry support. This segment of the tree is where players truly learn the balance between firepower, protection, and mobility.
Variant Specialization and Playstyle
Within the Sherman line, distinct playstyles emerge. The “Easy Eight” variants excel in long-range duels with their superior turret traverse and powerful main gun, making them effective sniper platforms. Conversely, earlier M4 models with their shorter barrels are better suited for close-quarters infantry support, using their high-explosive shells to suppress emplacements. The tree forces players to consider not just the vehicle in front of them, but the specific tactical role they wish to fulfill on the battlefield.
The Heavy Tank Endeavor: T26E4 and Beyond
As players climb the higher tiers, the USA tree transitions into the realm of heavy firepower with the T26E4 “Super Pershing.” This tank represents the American response to the increasingly thick armor of German heavy tanks like the Panther and Tiger. Equipped with a reinforced barrel and a devastating 90mm gun, the Super Pershing is a dedicated brawler designed to win armored confrontations at any cost. Its inclusion in the tree underscores the American doctrine of meeting overwhelming force with overwhelming force.
