The team were told by the Ukrainians they had been ambushed by a saboteur Russian reconnaissance squad.
Video shows them approaching a checkpoint from where soldiers begin shooting.
"The first round cracked the windscreen," wrote Ramsay, in an account of the horror incident.
"Camera operator Richie Mockler huddled into the front passenger footwall. Then we were under full attack.
"Bullets cascaded through the whole of the car, tracers, bullet flashes, windscreen glass, plastic seats, the steering wheel, and dashboard had disintegrated."
The team desperately try to take cover as the bullets hit their car, setting off sparks as they hit metal.
