1 The 505th Command and Control Wing supported the U.S. Army's Mission Command Training Program during its execution of Warfighter Exercise 21-1, the largest WFX ever conducted. The exercise directly trained over 5,300 joint warfighters and accomplished training objectives for 12 training audiences using more than two dozen different systems connecting seven sites across the country. WFX 21-1 was not initially planned for 12 TAs, but when WFX 20-4 and 20-5 canceled due to the COVID-19 pandemic; their TAs moved to WFX 21-1. To ensure U.S. Army warfighters were adequately trained for current and emerging mission sets, WFX 21-1 increased its training audience by over 2,300 personnel.
