M136 AT4

The M136 AT4 is the U.S. designation for an Americanized Saab AT4, a single-shot 84 mm shoulder-fired anti-armor weapon issued as a disposable launch tube. It gives infantry a lightweight close-range option against light armor, bunkers, gun positions, and buildings, and Ukraine has received AT-4 systems through U.S. security assistance during the Russia-Ukraine War.

Infantry WeaponsBGM-71 TOWHeavy anti-tank guided missileThe BGM-71 TOW is a U.S. heavy anti-tank guided missile built around tube launch, optical tracking, and command guidance through a wire or later radio-frequency link. Developed by Hughes and now produced and upgraded by Raytheon, it can be fired from dismounted launchers, HMMWVs, Bradley and Stryker vehicles, light armored vehicles, and helicopters, giving infantry and vehicle crews a long-range precision anti-armor weapon. In the Russia-Ukraine War, U.S. security assistance packages sent TOW missiles to Ukraine as part of the anti-armor mix used to offset Russian armored forces.
