For a moment, I felt sorry for the gunmen on the ground. The shape in the Merlin had to be a 7.62mm minigun, probably the GE M134, a Gatling-gun style weapon with a rate of fire up in the thousands of rounds per minute. Typically, one out of every six or eight shots was a "lit" round, a tracer. And even that minority was enough to make the stream of fire look like a solid bar of light.
