Quite a few of these made me laugh. Some military manuals are purposely written to either be understood by even the lowest possible education level, or fun... because some manuals can bore a person where they don't pay attention to what they are reading. For instance when the M-16 was first issued, the manual was very technical, so the military issued a comic book type manual with a female character that could put many Poser babes to shame. The idea was to engage the attention of the person reading the manual. :-)

My favorite because I just love the SR-71!!
