In the video at 1:56, there is the following statement which identifies the video as a petition directed at the Commander-in-Chief: "We appeal to the Commander-in-Chief to help us in this difficult situation" which was delivered in an unemotional tone.
A direct petition to the Tsar is a traditional "right" and one may consider this as a formality as it appears in every single video airing grievances of any kind - just a Russian thing, whatever.
In this context and with this bunch it is a bit more difficult to dismiss it as that: these guys have been fired upon by troops under the command of the Russian MoD, now they have made their petition and they may yet get fired upon again - they have been betrayed and will be betrayed again.
Anyone who knows anything about the end of Tsarist rule in Russia can make the connection with January 22, 1905, the Bloody Sunday, when the Imperial Guards of Tsar Nicholas II fired upon unarmed petitioners on their way to the Winter Palace.
The events of that day caused major upheavals in Russian society and eventually led to the 1917 revolution and the imprisonment and eventual execution of Nicholas II and his family.
These guys know this and so do other Russians, in particular Vladimir Vladimirovich, amateur historian he is, knows all about it.
No surprise that this video is apparently much talked about in Russian channels.
