tin hats

Doughboy head protection

Tin hats are metal helmets, especially the steel helmets worn by soldiers in World War I and later conflicts.

The term captures the helmet's basic protective function without military formality: The troops grabbed their tin hats and headed for the trenches.

In figurative use, putting on your tin hat means bracing for criticism or conflict.
