I visited the U.S. Army Heritage and Education Center, Carlisle, Pennsylvania, yesterday and viewed the "Photographic Record of 1st United States Ranger Battalion in training at S.S. Commando Depot, Achnacarry, Scotland," which is in the Lucian K. Truscott Collection. There are many splendid Signal Corps photos of Ranger training at Achnacarry, unfortunately, scanning of images by the public is not permitted. Nonetheless, I did have my camera and was able to take some decent photos of the photos. Major William O. Darby, MG Truscott, and LTC Charles Vaughan of the CBTC, Achnacarry, are featured in several of the photos. The attached resized image shows Lieutenant Alick Cowieson with Major William O. Darby. I created a Flickr album for all of my photos:: https://www.flickr.com/photos/63027303@N06/albums/72157696746794731 U.S. Army Signal Corps Photo, Credit AHEC. Dave
