The 68th Air Defense Artillery Regiment Distinctive Unit Insignia—more commonly called a DUI or a unit crest—was originally approved for the 68th Coast Artillery Regiment (Antiaircraft) on 26 July 1941. It was subsequently redesignated three times: for the 68th Antiaircraft Artillery Gun Battalion on 30 September 1946, for the 68th Antiaircraft Artillery Battalion on 5 December 1956, and for the 68th Artillery Regiment on 9 December 1958.
The insignia has been obsolete since it was rescinded with an effective cancellation date of 1 September 1971.
A gold pile (point-down triangle) simulates the appearance of a beam from a searchlight piercing a nighttime sky, an allusion to the Regiment’s extensive antiaircraft service. A fleur-de-lis at the top is red to denote the service of the 68th Coast Artillery in France during the First World War. LOLAMY, the Regiment’s motto, is taken from the Navajo language and translates into English as “Can Do.”
The organization was originally constituted on 1 June 1918 as the 68th Artillery (Coast Artillery Corps), but as mentioned earlier it would serve in an Antiaircraft role extensively throughout its history. During World War II, the unit (and others in its lineage) took part in eight campaigns in the European-African-Middle Eastern Theater, beginning in Sicily and ending with the Central Europe offensive at the end of the war; it was also awarded Arrowhead devices (one per campaign) for taking part in an assault landing in the Anzio and Southern France campaigns. It would also fight in all ten of the named campaigns of the Korean War.
