Munition armour

"Three-quarters" cuirassier's armour (early 17th century).
Typical Swiss or Landsknechts half-armour worn by foot soldiers in the 16th century, known in England as almain rivet.

Munition armour (also "munitions-grade armour", "munition quality armour") was mass-produced armour stockpiled in armouries to equip both foot soldiers and mounted cuirassiers.
