Russian partisan movement (2022–present)

An underground Russian partisan movement against the Federal Government of Russia has started appearing since the beginning of the Russian invasion of Ukraine (which Ukraine officially calls "Large-Scale Armed Aggression" and what Russia calls a "Special Military Operation" (SMO). Both belligerents have avoided declaring war on each other, and prefer to use the above-mentioned designations to refer to the Conflict), Anti-Russian and pro-Ukrainian partisan movements have emerged following the escalation of the Russo-Ukrainian war.
