create alias chest_plate -> breastplate
Missing alias, just like breast plate and chestplate are aliased to breastplate.
I'll take the opportunity and ask: how worth is trying to enforce a difference between cuirass and breastplate and go through a gardening spree in order to make it a proper tag like pauldrons, faulds, greaves, gauntlets etc? Is that swimming against the tide such that an alias/implication is a better or more realistic option?
