North Korea may help the DPR and LPR with weapons and equipment if such a request is received. And this is not ruled out, given that the DPRK has officially recognized the sovereignty of the republics.
Among the unique weapons, experts single out the North Korean 107mm multiple rocket launcher system. It is almost a toy launcher, which can be mounted on a car. Even women and teenagers would be able to use it.
In addition, North Korea has its own counterpart, HIMARS (with a range of 200-250 km) and multi-purpose tactical missiles with remote control.
