This series is comprised of materials relating to A Battery of the 206 Coastal Artillery (AA). These materials include one volume of photographs, one volume of negatives, and a booklet compiled by Don Drake featuring photographs of the unit in the Aleutian Islands. The images date from 1941-1942, and feature scenes of the unit stationed in the mainland United States and in the Aleutian Islands during World War II. Among the images are photographs of the Japanese attacks on Dutch Harbor in early June 1942; however, these images were apparently not taken by Obsitnik, who was at nearby Morris Cove at the time of the attacks. Nevertheless, a majority of the other photographs of A Battery were taken by Obsitnik.
