What's a word that means "thing that is held or worn during battle to protect oneself from injury and/or to inflict injury on others"?
To better explain this question, allow me to give an analogy. Foxes, squirrels, whales, and kangaroos are all mammals. The word "mammal" is the classification that contains with it those previously mentioned four animals.
What would the word be that includes swords, daggers, breastplate, shields, helmets, etc.?
The way I want to use this word is in the following sentence:
"Today, we will be studying medieval French ___, starting first with swords and other handheld weapons, continuing to shields and other handheld items used for defense, and finishing up with armor that is worn for defense, such as helms and breastplates."
