US vs Iran
SPG-9 Iran manufactures a copy (under licence?) of the SPG-9 anti-tank recoilless gun. “The SPG-9 Kopye (Spear) is a Russian tripod-mounted man-portable, 73 mm recoilless gun developed by the Soviet Union. It fires fin-stabilised, rocket-assisted HE and HEAT projectiles similar to those fired by the 73 mm 2A28 Grom low pressure gun of the BMP-1 vehicle. The projectile is launched from the gun by a small charge, which gives it an initial muzzle velocity of around 250 m/s to 400 m/s. The charge also imparts spin to the projectile by a series of offset holes in the launch charge. Once the projectile has travelled approximately 20 meters from the launcher a rocket motor in the projectile ignites. For the PG-9 projectile, this takes it to a velocity of 700 m/s before the motor burns out. 
TOWSAN-1 (AT-5 Spandrel) This wire-guided anti-tank weapon was developed in Russia. Iran began making a copy in 2000. . This system is designed to engage moving and stationary armoured targets provided with explosive reactive armour (ERA) protection. The KONKURS- M system can be carried by armoured wheeled and tracked vehicles. The 9P135M1 launcher can be provided with a thermal imager for night or poor visibility conditions.
When fitted with the thermal imager, which weighs 9.6 kg, it allows engagements at ranges up to 2500m. The launcher is designed to launch the 9M111, 9M111M, 9M113, and 9M113M missiles.
