Infantry Weapons9M113 KonkursSACLOS wire-guided anti-tank guided missileThe 9M113 Konkurs, NATO reporting name AT-5 Spandrel, is a Soviet wire-guided anti-tank guided missile family built for infantry launchers and vehicle mounts such as BMP-series vehicles and the BRDM-2-based 9P148. Its SACLOS guidance, 135 mm missile body, and 4 km class engagement range kept it useful after the Cold War, including documented employment in Ukraine and Armenian/Artsakh 9P148 Konkurs losses during the 2020 Nagorno-Karabakh fighting.

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.
