Ethyl Alcohol

Medicinal grade Ethyl Alcohol, chemical formula MED34-CH3CH2OH is a standard drug carried aboard UNSC starships and facilities. It is a flammable, colorless, mildly toxic chemical compound with a distinctive perfume-like odor, and is the alcohol found in alcoholic beverages. It has a number of medical uses as well, though these uses were never specifically enumerated upon.

Corporal Locklear was very aware of these facts, and managed to find the alcohol stores on the UNSC Gettysburg shortly before his death in the explosion of the Forerunner Crystal.
