Dear Mr. Schneider,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 3 series titled U.S. Army Recruiting Posters, 1986-2003; "Army Strong" Public Service Advertisements, 2007; and Army Reserve Officer Training Corps Recruitment Posters, 2003 in the Records of the United States Army Training and Doctrine Command (Record Group 553) that were created by the U.S. Army Accession Command. Some records are digitized and available in the Catalog but not all. For access to and/or copies, please contact the National Archives at College Park - Still Pictures (RDSS) via email at firstname.lastname@example.org.
We hope this is helpful. Best of luck with your research!
