Forest Park, IL, 424th Military Intelligence Detachment (Strategic), [ND, but ca. 1990]. Folio (28.0 x 21.5 cm). 314 pp.; several illustrations. Blind grey wrappers.

A very rare and probably unpublished work. It describes and illustrates 47 different snake species, their distribution, habitats, behaviour, clinical symptoms of their bites, and available antivenoms. This copy is in photocopy, printed on one side, and including several handwritten additions and corrections. Probably used for review. This work is not dated, but the youngest reference is from 1989. Colonel John C. Regner is not mentioned by Adler. There are no records of this work on the internet.
