TOG.

This is coolbert:

These guys back during the days of the old Soviet Union were KGB Second Department as far as I remember counterintelligence internal within the Soviet Union.

Now called FSB! Different nomenclature but the mission still continues

"New FSB groups arrive in occupied south of Ukraine to search for partisans"

"partisan: A partisan is a member of an irregular military force formed to oppose control of an area by a foreign power or by an army of occupation by some kind of insurgent activity."

From "Ukrainska Pravda" December 8, 2022.

"New groups of the Federal Security Service of the Russian Federation (FSB) have arrived in the temporarily occupied south of Ukraine to uncover the Ukrainian partisan movement."

Source: "National Resistance Center"

Details: "New FSB groups will be assigned the tasks of carrying out signals and electronic intelligence, including intercepting calls, monitoring Internet traffic, and jamming signals during the movement of Russian military equipment."

FSB mission evidently radio intercept and triangulation to discover communications and  locations of the various partisan groups.

"The National Resistance Center recalls that the Russian secret services have started hunting down partisans. The so-called temporary operative groups (TOG) were created in the temporarily occupied territories to search for partisans. These groups consist of employees of the counterintelligence department of the FSB and representatives of various services."

Ukrainian partisan activity the occupied territories must now have be seen as a serious threat to Russian rule and military activity. If they were not so the FSB would not be committing resources as they are now.

To what extent the Ukrainian Army had organized partisan units to be employed in case of Russian attack I just cannot say. Sounds like these units are similar to what the NATO calls GLADIO operations. Partisans during a time of crisis already trained becoming active and wage guerrilla warfare in in the rear area of an advancing enemy.

Ukrainian military from my perspective seems to be very well organized and perhaps has thought through the entire aspect of partisan activity well in advance. There is indeed a very long history of partisan warfare in that part of the world. Partisan warfare as being successful too when waged in  conjunction with conventional warfare.
