This page from a 1942 U.S. Naval Training School recognition manual trained sailors and aviators to identify the Grumman F4F Wildcat, the US Navy's primary carrier-based fighter in the early years of the Pacific War, from multiple angles and attitudes. Silhouette recognition training such as this was essential for reducing friendly-fire incidents and enabling rapid threat assessment in combat. This example survives as part of a personal wartime collection connected to the 345th Bomber Group stationed on Ie Shima. Project: 218069
