Historic Flag Signaling Drill from 1915-1920

This photograph captures a wig-wag practice session dating back to between 1915 and 1920. The term wig-wag refers to a signaling system that uses flags or lights to convey messages over long distances, particularly important in military contexts. The session depicted illustrates the training methods employed during this era, showcasing the focus on communication and coordination within military operations.

The image is part of a series by the Bain News Service, known for documenting significant events and practices of the time. This particular practice likely involved personnel being trained in the intricate movements required to operate the signaling system efficiently. Understanding these historical training methods sheds light on how communication was managed before the widespread use of radio technology, which transformed military operations in the decades to follow.
