From the BBC's interview with Ken Crunk, editor of the US Army magazine Preventive Maintenance Monthly, currently under investigation by JK Rowling's lawyers for copyright infringement:

"The drawings do not look like any of the characters from Harry Potter ... We are very careful when we do these things not to copy images because that would be illegal."

Personally, GC can't decide which is saddest:

a) Our military's ignorance concerning issues of legality.

b) Our military's winning knack for losing battles.

c) Our military making helmets out of foil, following step-by-step instructions illustrated by magical school children.
