that is absolute nonsense...none of the rebels were trained to fire that sophisticated piece of military equipment. A russian military person fired it ....period. Russia is 100% liable for this disaster and we should NEVER let them off...
They can fire them. I was reading today that it isn’t that hard. Since everyone there is from Ukraine, it would stand to figure that some of these guys were in Ukraine military prior to the coup.
Some of the rebels might have been in the old Ukranian military before the split between east and west. So they could have gotten formal training from Ukraine.
