Royal Australian Air Force Group Captain Darrell May, Director of Space Forces, reviews the orbital warfare mission plan at the 392d Combat Training Squadron Battle Lab during SPACE FLAG 23-1 at Schriever Space Force Base, Colorado, Dec. 13, 2022. May served as a senior leader for the first vulnerability period in the exercise. During three two-day exercise vulnerability windows, where each included mission planning on the first day and then simulated combat operations on the second day, the training audience practiced their actual procedures to increase readiness to win in a European conflict.
