Rigging with broken/separate mesh???

As the title say how do i rigged separate objects with one bone setup?? For example my character has armor but the armor is separate and i need it that way but i want it in the same rig as the body. Tnx for the help:))))

Put your rig into pose mode. Select an object, shift select a bone, Ctrl-P (set parent to) > Bone.

Edit: Also in properties panel of selected object…
Properties > Object > Relations > Parent > (armature name) > Bone > (bone name).
