Making 'Prop' Entities
From The DarkMod Wiki
Prop entities are stored in tdm_prop_wearable_items.def and tdm_prop_items.def. 'Wearable_items' are things an AI might wear (headgear, belt-buckles, etc), while 'prop_items' are for things an AI would carry or attached to a belt (weapons, torches, keys, potions, etc).
