Hawkins directed his forces into luring Chimeran forces into direct combat with his army in a pincer move, while providing an ample diversion for a Search and Recovery team led by Nathan Hale and Dr. Linda Barrie to successfully penetrate the Chimera base near Hot Springs and acquiring nuclear fuel cells from the facility.
