U.S. Marine Corps Col. Quintin Jones, commanding officer of Marine Air-Ground Task Force 23, observes Marines execute Range 400 during Integrated Training Exercise (ITX) 4-22 at Marine Corps Air-Ground Combat Center, Twentynine Palms, Calif., July 23, 2022. Range 400 is used to conduct company-level live-fire training in a deliberate assault against prepared defensive positions. Marines and Sailors with MAGTF-23 maintain various civilian careers, but continue to answer the irrational call to service in the Marine Corps Reserve, staying combat ready through challenging, realistic training.
