Mission 10: Battle at Red Slate

"With the Covenants forces exposed, Spartan Palmer and the 23rd Armored Cavalry's massive column of Scorpions and Grizzlies rushed across the Red Slate plateau on a collision course with several Covenant tank battalions. Only a UNSC counter-offensive would prevent Faraday from being crushed between the northern and southern front. The 23rd had brought eighty-six vehicles to Draetheus-V. After the battle at Red Slate, there were only eight functioning vehicles left."
