Gunnery training was many ways like an early form of video games. It included using a movie (seen being loaded in the previous photo) so that gunners could then use practice guns to “shoot” at virtual “targets.”
Here a WAVE training in gunnery instruction is at the trigger of a gun known as a “jamhandy.”
The photo comes from the Schlesinger Library at the Radcliffe Institute for Advanced Studies.
