Armure vs. blindage
The French words armure and blindage both refer to protective layers, but they are used in slightly different contexts. Armure generally refers to body armor, historically or modern, whereas blindage is commonly used for protective coverings in vehicles, buildings, or other structures.

B1A suit of armor typically worn by warriors during battles in historical contexts, or protective gear worn by individuals.

Summary
In summary, armure refers to body armour and personal protection used historically or in modern times for personal safety, while blindage refers more to vehicle or structural fortification against external attacks such as bullets and bombs. Their use emphasizes the nature of the protection - whether for an individual or for a larger entity such as a vehicle or building.
