My late father gave me a couple of 1970's era paperback manuals from a visit to Camp Pendelton. There were several one page comic book style pages in them illustrating things that should not be done with Marine property.
One regarded where not to park a certain all terrain vehicle that was prone to not starting if it were left parked on an angle. The carb float would stick and you would be screwed if you really needed to move out.
I wish now that I had kept those gems. From what I'm told, using comics to help train Marines has a long history, with many of the best examples dating to the Second World War. Artists from Disney and Warner Bros. would produce some of them.
