During World War II, the U.S. military needed to train as many men as quickly as they could. In those demanding circumstances, many new training methods were born, and most of those ideas focused on providing information using oversized graphic presentations. Posters, training films, and film strips were created (and supported by workbooks) for many topics — and particularly for small arms.
The concept of the double-size training aids took this idea one step further, providing a tactile, and instantly self-explanatory educational tool.
The visible operational features in the sectional training aid were color-treated to look like the real thing. The device is hollow and constructed of light aluminum, so although massive, it is not heavy. Simulated ammunition, made of plastic, was used to demonstrate how the magazine was loaded. A transportation/storage case was provided, and the plywood top of the case could be removed and used as a display base.
The M24 training aid is an oversized M1 Garand rifle. It is 86″ long, 19¾” high, and 17″ wide.
