The 440th has one senior officer in charge of the wing and three group commanders (operations, maintenance and mission support) and 1 medical squadron commander who oversee the 19 units that make up the 440th.  The units that make up  the 440th are manned by about 1,400 reservists and civilians.  About 220 of the civilians employed by the 440th are "ARTs", or Air Reserve Technicians.  An ART's civilian job requires the man or woman to be a member of the Reserve. 

The majority of Reserve training is completed during unit training assemblies or "UTA" weekends. Each reservist must complete one weekend a month of training each year.  Besides two days of training each month Reservists must schedule and complete a minimum of 15 days of training during a calendar year.  Reservists may also opt for additional training to attend schools, maintain flying proficiency or to support special projects.
