Russian-backed Separatists in Ukraine fire 82mm Mortar Rounds with a Rocket Propelled Grenade Launcher (RPG,) for adaptive indirect fire. An innovative approach to bypass and evade the Organization for Security and Co-operation in European (OSCE,) Special Monitoring Mission to Ukraine. The video showcases the testing of this practice by Russian-backed Separatists.

A similar methodology is used by the Iranian Islamic Revolutionary Guard Corps (IRGC.) Field-crafting an RPG-82mm hybrid can be interesting, but hardly compares when an army has access to the actual munitions. For instance in comparison to an anti-personnel OG-7V round, fragmentation, or thermobaric round.

The method is also, coincidentally a 1980s Central American Crisis tactic of the leftist guerrilla forces, such as Farabundo Martí National Liberation Front (FMLN) . . . When Communist threats courtesy of, the Cold War battles for the third-world between America and the U.S.S.R. were active.

Many, but not all mortars have complex fuses, which require a certain threshold of acceleration to be attained in order to prime and arm the mortar for detonation. Once fired, most mortar rounds must reach its designated threshold to detonate. Meaning that only when most mortar rounds have enough force/kinetic energy behind it, would it detonate. As the designed force threshold typically projects the mortar round at a great enough of a distance so that it would not be a danger to those firing it.

A variety of RPG rounds can also be modified with this type of mortar, by removing the auto-destroying fuze and then using it as mortar round. The Mujahideen in Afghanistan used a similarly technique, with a modified time-fuse mortar as an anti-infantry weapon against the Russians – firing the RPG-mortar at an aimed, high-arc so the device would explode in an air-burst of their target.

There is not much context offered in the translation of the Russian-backed Separatist:

Some random chatter spiced with plenty of swearing at the beginning.
Others encourage the weaponeer to go further away from the house and the rest of the group (because this improvised mine-grenade looks safe as fuck.)
Then the group becomes angry and rabbles, as their faces could be filmed (out of fear of de-anonymization.)
“Aim higher!”
“Fire!”
Pfsshh
*Laughing*

To their concern of hiding faces, it is not just because they might be Russian citizens and soldiers. They may be locals, and other Ukrainians will be able to identify them.
