I doodled it while in a lesson on The Laws Of Armed Conflict. You know, rules of engagement, Geneva convention, war crimes kind of stuff. (I'm not showing off that my work is awesome, at all. Honest.)
Here 'tis. Incidentally, the cover on the pad which I drew this on states that the pad is a:
FIELD MESSAGE BOOK
(For the use of officers and
non-commissioned officers)
This book is ruled in 6mm squares.
Ah the military!
