Noticed on the low chassis set, a multi-guided rocket launcher was created akin to erstwhile specified structures. A rocket launcher was placed on the hull ceiling of the MT-LB armored transporter, this time derived from the wheeled Grad-1. This connection has not been seen so far, which may indicate that it is an improvised structure, which was created in 1 of the military workshops. The launchers could have come from damaged Grad-1 or were in 1 of the military syntaxes. In this way, the Russians created a caterpillar variety of Grad with the anticipation to fire targets over a distance of about 15 km.
