Apparently not a hoax, Foreign Policy reports:

Buried on the military’s secret computer network is an unclassified document, obtained by Foreign Policy, called “CONOP 8888.” It’s a zombie survival plan, a how-to guide for military planners trying to isolate the threat from a menu of the undead — from chicken zombies to vegetarian zombies and even “evil magic zombies” — and destroy them.

“This plan fulfills fictional contingency planning guidance tasking for U.S. Strategic Command to develop a comprehensive [plan] to undertake military operations to preserve ‘non-zombie’ humans from the threats posed by a zombie horde,” CONOP 8888’s plan summary reads. “Because zombies pose a threat to all non-zombie human life, [Strategic Command] will be prepared to preserve the sanctity of human life and conduct operations in support of any human population — including traditional adversaries.”

Navy Capt. Pamela Kunze, a spokeswoman for Strategic Command, acknowledged the document exists on a “secure Internet site” but took pains to explain that the zombie survival guide is only a creative endeavor for training purposes. “The document is identified as a training tool used in an in-house training exercise where students learn about the basic concepts of military plans and order development through a fictional training scenario,” she wrote in an email. “This document is not a U.S. Strategic Command plan.”
