As I mentioned when the news of massacre of Bucha first came out...
Russian 35th CAA is not the only unit that committed those crimes.
The Russian 76th Guards Air Assault Division, three units from Ramzan Kadyrov's Chechnyan thugs, and Unit 3179 within the elite Vityaz (under the National Guard) also left evidence of their own involvement.
