A surface-to-air missile and trouser-S1M (SAMG) system is mounted on a MZKT-7930-312 chassis, spotted on a public road. The choice of the Belarusian chassis is quite obvious, in light of the relatively frequent incidents involving trouser systems mounted on the KamAZ-6560 chassis tipping over on their sides due to their high center of gravity. This is also one of the reasons behind the development of the upgraded SM-pants on the KAMAZ-53958 chassis.
