> “Such suits of armor were recorded in palace archives—in the equipment lists of those complete or needing repair. This indicates they were supplied at the expense of palatial centers,” says Flouris. They were bloody expensive and thus financed, maintained, stored, and issued during emergencies by the state. Mycenaean palatial centers disappeared around 1200 BCE, and the supplies of Dendra-type armor disappeared with them.

So... it sounds like the armor was kind of ceremonial in a way. Even if it was functional it didn't sound very practical - it only existed as a projection of force and wealth in defensive situations.
