1. Veteran Rifle Squad
   A surprisingly effective choice. With two Browning Automatic Rifles (BARs), rifle grenadiers, and solid health and regen stats, these squads offer a noticeable firepower boost over standard infantry. They’re accessible early, affordable, and lead into elite units like the Rangers.

2. 101st Airborne
   This is arguably the best infantry unit for the USA. With two BARs, two Thompsons, a 30-cal machine gun, M9 bazooka, and multiple grenade types, the 101st brings immense firepower. Their health and stamina are excellent, making them capable of punching above their weight in nearly any combat scenario.

3. 3-Inch Gun M5 (M1 Carriage)
   An exceptional anti-tank asset. With 161mm of penetration and a wide gun shield, this towed gun provides consistent reliability against medium to heavy armor. It’s better than its counterpart, the M6, in terms of both performance and survivability.

4. 75mm M1A1 Pack Howitzer
   This is the second variant with a gun shield and heat rounds. Lightweight (two tow weight), mobile, and extremely versatile, it handles light armor, infantry, and emplacements efficiently. A must-have for a cheap anti tank weapon that can still stay mobile with a cheap truck.

5. M16 MGMC Quad .50 Cal
   A terror against infantry and light vehicles. The quad-mounted .50 cals on a half-track platform offer a devastating rate of fire. It also serves as effective anti-air and suppresses enemy units with ease. It’s a machine gun on steroids… because it’s 4 heavy machine guns.

6. M20 Armored Utility Car
   This seemingly unremarkable unit hides a secret—it carries a bazooka. Light, fast, and equipped with a .50 cal, it offers early anti-tank capabilities when infantry may lack punch. It’s also cheap and has decent survivability.

7. M3 Stuart (Late Variant)
   What sets this variant apart is its complement of five .30 caliber machine guns. With a 37mm cannon, decent armor, and speed, this tank becomes a mobile bullet storm. An excellent light tank for early and mid-game, especially at suppressing infantry.

8. M4A3E8 Sherman 76mm (Field Mod)
   Strong armor, excellent penetration, and a massive ammo supply for its .50 cal make this the best Sherman variant. It’s a top-tier medium tank with improved survivability and offensive capability.

9. 90mm GMC M36
   This tank destroyer brings heavy firepower with 171mm penetration. Although open-topped and vulnerable to HE, it excels at ambushes and long-range AT roles. A tank hunter’s dream. Can prevent enemy tanks from advancing over a wide area.

10. 105mm HMC M7 Priest
    A self-propelled gun with solid high-explosive power and mobility. Though open-topped, it brings potent indirect fire and versatility to American forces, making it a great late-game support choice.
