The article is factually incorrect. All the Georgian tanks in Tsinvali has been destroyed by the militia and peacekeepers on August 8 using RPGs. 19th division approached the city in the evening of August 8, but the were busy eliminating the Georgian artillery position around and only entered after 9 am next day.
Of 120 tanks destroyed I really doubt many were by ATGM or other tanks.
Apart from 6 destroyed by RPGs in Tsinvali the rest has been bombed from the air (usually abandoned the the fleeing troops at the time) or demolished by the advancing infantry.
This whole event is very interesting to me. Do you know of any good documentaries or Youtube videos on the subject?
I am not interested in Pro-Russian or Anti-Russian propaganda but rather how the logistics of something like this could go down in the modern era.
