An idea was that mothers had to convince their kids to lay down arms. I think about 90% of Ukrainian military bases were captured this way as far as their army is mostly a teenage conscript force. From the video a bus was driven by a guy in camo wearing a St. George ribbon which is typical for the rebels and for that reason a garrison opened fire on the bus.
No. That was not the idea. The idea was a media event where journalists and mothers get killed. That is why they loaded them on a bus and had it drive at midnight at the base that 50 soldiers were guarding. You claim that the fire was opened because of the colorado beetle ribbon the driver was wearing, but this is ridiculous. No one could see this small detail at midnight. Handlers knew what is going to happen if you drive a bus at the military base at night considering what the situation in Ukraine is now.
