Who is Captain Mike Steele from Black Hawk Down: A Story of Modern War and what is their importance?

Captain Mike Steele was the leader of the four Ranger chalks that would provide support on the ground to the Delta Force who would raid and arrest the targets in Mogadishu. Late in the day on October 3, Steele and his remaining Rangers would team with a group of Delta Force soldiers still on the ground and make their way on foot to the first crash site. The Delta Force soldiers were trained to act individually in battle and would quickly move up ahead of the Rangers.
