 Click here to find Relatives Unit Info

The OOB is provided for those interested in what shoulder patch their relative may have worn.  I do NOT have unit histories on any of the several hundred units listed in the OOB. If you want info on any specific unit, use the green button above this red text. 

The following non-divisional units were all elements of 9th U.S. Army from 5 September 1944 - 5 May 1945. If your relative was in any of these units, with the following exceptions:

Tank Battalions

XVIII Corps Artillery

Cavalry Group Hqs, Mechanized

Chemical Battalions, Motorized

Tank Destroyer

Army Air Forces

2nd and 5th Ranger Infantry Battalions

LCVP Unit Number 3 (USN)

Then he or she officially wore the 9th U.S. Army patch. This is not to say that some of these 9th U.S. Army MAY have created and worn a patch of their own, but I have found no documentation, photographs, or interviews to the contrary. Some of them may have their own distinctive unit insignia.
