It is known that russian occupiers have begun to manufacture portable home-made rocket launchers called Kozerog BRT, with one, two or even three launchers for firing 122-mm rockets for the BM-21 Grad MLRS.
It is alleged that russians use rockets that did not work during firing from the BM-21 Grad launcher. It is also stated that there are quite enough such unexploded rockets.

At first glance, these russian products, called Kozerog BRT, resemble Soviet Grad-P rocket launcher. The difference is that the "original" had only one launcher, while russian version has two or three launchers.
However, several questions arise. It seems that russians decided to use the original 9P132 launchers from Soviet Grad-P systems, only adding a few barrels and slightly modifying the carriage. This raises the question: did russians use the 9P132 launchers from the Grad-P systems from their own stockpile, or they get them from Iran. Because Iran also used to produce similar systems.
Moreover, if russian invaders from the 1st and 2nd Army Corps have been using Grad-P systems in the temporarily occupied part of Donbas since 2014, it is means that russia barely may have a significant number of such systems for now.
Another question of what kind of missiles russians can actually use for the aforementioned Kozerog BRTsystems.
If we assume that occupiers use 9P132 launchers from the Grad-P systems, it turns out that usage of regular rockets for BM-21 Grad MLRS can be problematic. Because the 9P132 launcher is slightly shorter than the BM-21 launcher. 9M122M with a body length of 1.95 meters (range - up to 10.8 km), as well as 9M122MD shortened rockets (range - up to 15 km) were designed specifically for the Grad-P systems.
However, there is also an amendment that during the testing of various versions of 9P132 Grad-P systems, it was allegedly confirmed that they could fire standard BM-21 Grad shells, but this did not allow disclosing the characteristics of these munitions.
However, it is necessary to take into account the fact that russian invaders demonstrate their intention to saturate their troops with portable rocket launchers as a kind of supplement to regular rocket artillery.
Earlier Defense Express reported that Ukrainian FPV-drone had destroyed russia's latest 2S40 Floks mortar.
