Check the listing for details. USA DOD Rockwell International Security Shoulder Patch (DOE Nuclear Facility). Condition: New. Listed at 19.95 USD. New and original, vintage shoulder patch from Rockwell International Security. Now defunct, Rockwell was a major manufacturing contractor for the DOD and as such were required to provide highly trained security personnel at their facilities. Believe this patch was worn specifically by security units at DOE Nuclear Facilities. The company was split up in 2001, so this is a collectible item only and carries no authority with it. Embroidered design on stiff fabric, with a merrowed border. We do combine postage, so your shipping costs will not increase by much if you buy more than one item.
