Since the activation of the 25th Infantry Division on 1 October 1941 a considerable number of units have been assigned to the Division. Some units have been assigned for as long as the Division has been active but many others were assigned for shorter periods of service. Thousands of soldiers who can proudly call themselves Tropic Lightning veterans have served with these units.
It is the objective of the Association to provide Tropic Lightning veterans with information on the units that have been assigned to the Division from 1941 to the present. The information would include the unit's lineage and honors, its insignia, a brief unit history and the current status of the unit. As the list of units that have been assigned to the Division since 1941 is a long one it will take time for the project to be completed. In response to specific requests by veterans groups, information will be furnished on specific units that, while assigned to other organizations, were in varying degrees associated with the 25th Division in combat operations. See Associated Units. The following table displays the organization of the 25th Division during World War II, the Korean War and Vietnam and lists the units which were assigned to the Division during each war. The 25th Infantry Division was credited with 4 campaigns in World War II, represented by 4 bronze campaign stars on the Asiatic-Pacific Campaign ribbon. The Division's 10 Korean campaigns are represented by two silver campaign stars (one silver equals five bronze campaign stars) on the Korean ribbon. The Division is credited with 12 Vietnam campaigns, represented by two silver and two bronze campaign stars. |

Scout dogs also proved their value in night ambush operations giving the unit early warning of an approaching enemy. Read more about them.
