Table of
U.S. Divisions
and their
Regiments and Field Artillery & Engineer Battalions
and other Supporting Units

Followed by illustrations of the shoulder patches for every Division.

   This table lists the units within every US Infantry Division & Airborne Division.  The table lists the Infantry Regiments and Field Artillery Battalions and the Engineer Combat Battalion associated with each.   This table is useful for quick reference, as there are several websites that has details on individual divisions.
   In 1940, the US Army adopted the "triangular division" which meant that each Division consited of 3 regiments, which in turn consited of 3 battalions.  Each division had 3 artillery battalions but this was later increased to four. The Medical, Signals, and Quartermaster Companies were smaller support units and are not listed in this table. However the divisions followed the same general rule in their numbering of these support units.  There were many exceptions to this rule.

  The general rule was that the support units of a division consisted of a Reconnaissance Troop, a Signal Company and a Quartermaster Company that were identified with the same number as the Division. The Medical Battalion generally used the same number as the Engineer Battalion, as I have listed in the table. The Ordnance Company identification was the same as the Division number with a "7" prefix.
    Example:   Supporting units of  88 Division were:  313 Engineer Btn, 313 Medical Btn,
           88 Recon Troop, 88 Quartermaster Co., and 788 Ordnance Co.

How to use the Table: If you know a regiment number and are searching to find its parent Division, you can look it up in the Table or use the Search feature of your web browser. After using this table myself for several months, I have not found any errors.  I don't list all the Armored or Airborne divisions; only the ones that served in Italy.   Some artillery or engineer units may be missing as they were independant and reported to a higher command.

For a similiar list of the divisions of the German Army in Italy, late 1944:   Table of German Divisions.
 

Divisions marked in Red are those that served in the Italian Campaign, Sept 1943- 1945 (excludes Sicily).
Divisions in Green served in Western Europe. All others saw service in the Pacific, Philippines or
as training or occupation forces.

Cavalry and Armored Divisions are not listed. (But, 1st Armored is listed below.)
  Airborne Divisions are shown; some regiments transferred between Airborne Divisions,
         so this table may be inaccurate for campaigns of WW2.
  The 10th was the only Mountain Division in the US Army.  Its regiments were referred to
  as "Mountain Regiments".
   * 92nd Division had several units attached to it, including 366th Regiment and
          473rd and 442nd Combat Teams and their attached 522nd Field Artillery.
   + The 39th 'Delta' Division was formed from the Louisana National Guard after WW2.
           Some individual units did serve overseas, including 141 FA.
    102nd Cavalry Recon Squadron landed at Normandy and was the first US unit in Paris.

  Normandy Invasion - Divisions that landed on the first 2 days:
                                          1, 2, 4, 29, & 90 Infantry and 82 & 101 Airborne
  Battle of Bulge - Divisions in the line on December 16:
                                 4, 28, 83, 99, 106, & 109 Infantry & 9 Armored
  Black Divisions:  92nd & 93rd Divisions were all-black divisions.

Ghost Divisions were fake units created as part of Operation FORTITUDE in order to
   decieve the enemy about our forces and the intent of the D-Day invasion.  A "ghost" army
   called the First US Army Group comprised 11 non-existent divisions under the command
   of General Patton.  They even had shoulder patches made for these Ghost Divisions.
   The division numbers missing in above table were some of these ghost division.
    The Ghost divisions included:
                  14, 22, 50 & 55 Infantry Division
                  18, 21 & 135 Airborne Division

   Seperate Units
     Many other regiments and artillery battalions existed but were not part of any of the
  organized divisions.  These units were 'attached' to divisions for support.  Some were
  specialized, such as paratroopers(PIR) or heavy artillery or coastal artillery.
    I will try to list some of these as I identify them.  There were hundreds of field artillery
  battalions that were attached to corps or armies---too many to list.  I will try to list
  the ones that served in the Italian Campaign.
503 PIR   Parachute assault at Corregidor in Feb 1945.
504 PIR   Originally part of 82nd Division, later detached.  Salerno, Italy 1943.
507 PIR   Transferred to 82nd Division.  Landed at Normandy.
509 PIR   Salerno & Anzio.  509th was in first airborne assault at Oran, Nov 1942.
59, 68 & 69 FA   Field Artillery attached to 36th Division in Italy, Jan 1945.
980, 987, 190, 187, & 200 FA   Landed at Normandy as seperate unit.
 9 & 14 FA
630 CA AA
   Coast Artillery units.  Some Costal Artillery converted to Anti-Aircraft or Automatic Weapons units.  See Reference, below.
  {PIR = Parachute Infantry Regiment or paratroopers}
