| Under the old 
      army organization virtually every squadron had a different numeric 
      designation.  This caused a great deal of confusion.  Under the 
      new wing organization, most of the Assigned Squadrons carried the same 
      number as the Assigned Wing (For Exceptions, see *'s below).
 Combat squadrons (Bomber, Fighter, Recon, & 
      Missile) Maintenance a separate numeric identity as they were often 
      transferred from one wing to another.   Tanker Unit's may or may 
      not have the same designation as the wing). Example: The 380th BW  
      had five combat units: the 528th, 529th, 530th and 531st Bombardment 
      Squadrons, the 380th Air Refueling Sq, (AREFS)  and later: had the 
      310th AREFS assigned.  The tanker squadron having the same same 
      numeric designation as the bomb wing was strictly a coincidence. Special 
      Mission Units were, also assigned to the 380th BW from 1962 to 1964 the 
      4365th Post Attack Command & Control Squadron, with Special purpose 
      B-47's. Between 1962 & 1958 the 380th Supported the 556th Strategic 
      Missile Sq. a  Atlas ICBM Missile Sq.  While operating FB-111A's 
      the 380th had the 4007th Combat Crew Training Squadron assigned.
 For example, the Flying Wing Maintenance units 
      were the Periodic Maintenance. Sq. (Later:) Organizational Maintenance Sq. 
      Later: R/D as  Aircraft Generation Squadron (Flight Line Level 
      Maintenance, Inspection Docks, Base Flight/Transit Alert, & Aerospace 
      Ground Equipment-Non Powered), the  Maintenance Squadron.*, later: 
      Field Maintenance Squadron. (Later R/D:) Equipment Maintenance Squad.& 
      finally Maintenance. Sq. (Aircraft & Engine Systems and Specialty Shops 
      (including Structural Repair), and Aerospace Ground Equipment -Powered), 
      the Armament & Electronics Maintenance. Sq.  (Later:) Avionics 
      Maintenance. Sq. and Component Repair Squadron (Aircraft Electronic 
      Systems (Minus - Electrical Shop) (Missions Systems, Comm/Nav, Armament** 
      & Defensive Systems), In specified B52 / DC-130 Recon Units a Airborne 
      Missile Maintenance. Sq was assigned to Maintenance AGM-28's Hound Dog,  
      ADM-20's  Quail and Ryan Freebee RPV's, and the Aviation Depot Sq.***  
      (Later:), Munitions Maintenance squadron .  (With the Implementation 
      of POMO Maintenance Concept. The MMS Function is Merged and assumed by the 
      Equipment Maintenance squadron . Small & Forward Units with Maintenance 
      requirements had a Consolidated Aircraft Maintenance Squadron (CAMS), 
      (whose history is traced thru the Field Maintenance Squadron****) with all 
      Maintenance functions assigned.
 Additional Maintenance. Units were added as required to 
      support special requirements
 
 * Early SAC units had Maintenance Squadrons or Maintenance & Supply Group. 
      where the Maintenance was redesignated as Field Maintenance Squadrons Most 
      SAC Units had Units activated as FMS's.
 ** AEMS at Bases with No Munitions Functions had Weapons Functions 
      assigned.
 *** All Maintenance Squadrons carried the same number designation as the
 wing assigned with the exception of nuclear ADS / MMS until 1 October 
      1972
 when all MMS were redesignated with the host wing number.
 ****KC-10 CAMS unit's were not  Linked to the FMS as the FMS's were 
      still
 Active at the time.
 
 Support groups were numbered to the Host Unit 
      numbers.  When the 380th Bomb Wing Activated at Plattsburg Air Force 
      Base, New York, it was supported by the 820th Combat Support Group. The 
      Base was designated to Support a Dual Wing Concept. A second B-47 wing 
      (308th BW) was designated to also be assigned to Plattsburg AFB, but was 
      delayed Activation. Because  the Base was to Host two equal units, 
      SAC Activated the 820th Air Division.  All squadrons within the Air 
      Base / Combat Support Group carried the same numeric designation - supply, 
      civil engineering,/ medical etc.  . When the 820th AD deactivated, 
      the 820th CSG and all 820th Support Squadrons were Redesignated as the 
      380th Combat Support Group and its support squadrons
 Support Squadrons Assigned & Later redesignation

 After reorganization of support functions Base ops  Functions 
      Merged with MAC
 Weather Detachments, Records, Training, & other Operations Functions  
      to
 form:  Operational Support Sq.
 
 * On SAC Bases SAC Kept assignment of the communication squadrons (Comm 
      Centers) as SAC Comm Sq's however the Air Traffic functions 
      were transferred to a AFCS Squadron. Some SAC Comm Sq. carried the 
      designation of the Host Unit Plattsburg  820th Comm Sq. Fairchild's 
      92nd Comm Sq - 92nd BW,  98th Comm Sq , 98th BW  however  
      Offutt had the 1st Aerospace Comm Group (SAC),  30th Comm Sq, & 31st 
      Comm Sq.- March AFB had the 33rd Comm Sq. - Andersen
 27th Comm Sq -Westover 18th Comm Sq, Barksdale  46th Comm Sq.
 
 Infirmary             
      Later:   USAF Hospital
 Dispensary            
      Later:   USAF Hospital
 Medical Group         Later:   
      USAF Hospital / USAF Regional Hospital
 
 
 Might just be the HQ's Bases had different Comm Squadron ID's from the 
      host unit.
 
 There are Exceptions to every rule   You asked about the 862nd 
      Med Group.  the 862nd CSG was assigned to Minot a dual wing Base   
      450 BW / 455 SMW  the 862nd CSG was activated Jan 62 the 810th AD 
      transferred from Biggs AFB, Texas in July 62. the 862nd remained until 
      1972 when base functions were assigned to 91st SMW the apparent thought 
      (i.e.: reading between the lines)  was the SMW was a more fixed in 
      location then a flying wing.  (At least that is my reading of the 
      exception)
