Translation of "breastplate" into Spanish

They would flagellate themselves before they put on their breastplates and went into battle! No.

Se flagelaban a sí mismos antes de ponerse sus corazas y salir a la batalla.

The knife probably didn't go in much past the breastplate.

El cuchillo probablemente no traspasó más allá del peto.

Although he's wearing a military breastplate, there's no actual suggestion that he's ready for action,

Aún cuando viste una armadura militar, éste no es un hombre que vaya partiendo a la guerra.
