Material or materiel:

Material and materiel are nouns that refer to resources. Material refers to goods and substances used to make something, or something’s constituent substances. Materiel refers to military equipment. Remember that personnel and materiel, two words that refer to, respectively, human and inanimate resources used by the military, both end in -el. This shared spelling is a useful memory tool that can help you remember this word’s usage case. Raw goods used for military construction projects could be a case where materials are used to make materiel.
