M1 Garand and M1 Helmet Pictures

[Harlan (Deceased)]

Below left is another view of the model 5 helmet during the trials. On the right is a WWI era German helmet.
The Army liked the extra protection offered by the Model 5 but from the side it looked too much like a German helmet.

We weren't at war with Germany at the time of the trials but they must have seen it coming.
