More launchers and missiles have popped up in the inventory of the Al-Nasser Salah al-Deen Brigades, which seceded from Hamas because of political differences. It is unknown whether other conventional armament was delivered alongside the ATGMs, but North Korea is also known as a major producer of MANPADS and rocket-propelled grenades, making it plausible some of these were exported as well.
The North Korean launchers differ in a few key areas. Most notably, the optics have been extensively modified. While the operator’s scope of the 9P135 (the lower scope in above picture) is similar to the operator’s scope on the Bulsae-2, the scope auto-tracking the missile (the upper scope in above picture) has been swapped for two separate smaller optics. The way this works is unknown, as is whether or not it constitutes an up- or downgrade over the original design. Lastely North Korea appears to manufacture their own distinctly shaped batteries, which likely does not affect the quality of the system.
