   The Differential Theory of U.S. Armed Forces (Snake Model)
  
   Upon encountering a snake in the Area of Operations (AO):
  
   a. Airborne: Lands on and kills the snake.
   b. Armor: Runs over snake, laughs, and looks for more snakes.
   c. Army Aviation: Has GPS grid to snake. Couldn't find snake. Back to
   base for crew rest and manicure.
   d. Ranger: Plays with snake then eats it.
   e. Navy SEAL: Expends all ammunition, several grenades and calls for
   naval gunfire in failed attempt to kill snake.  Snake bites the SEAL and
   retreats to safety.
   f. Field Artillery: Kills snake, but in process kills several hundred
   civilians with a massive TOT with three FA BDEs in support. Mission is
   considered a success and all participants (Cooks, Mechanics, Clerks,
   etc.....) are awarded Silver Stars.
   g. Marine Recon: Follows snake and gets lost.
   h. Combat Controllers: Guides the snake elsewhere.
   i. Para-Rescue: Wounds the snake in the first encounter, then
   feverishly works to save the snakes life.
   j. Air Force Fighter Pilot: Mis-identifies the snake as a MIG and
  engages it with missiles.  Crew Chief paints snake on airplane.
   k. Combat Engineer: Studies snake. Prepares in depth doctrinal thesis
    in obscure 5 series FM about how to defeat snake using counter mobility
assets.  Complains that maneuver forces don't understand how to  properly
conduct doctrinal counter-snake operations.  (Engineer School tries to hide
the fact that M9 ACE proves ineffective against snakes).
   l. Special Forces:  Makes contact with the snake, builds rapport, wins
  its    heart and mind, and then trains it to kill other snakes.
  m. Ordnance:  ID snake as having improper scales, deadlines snake and
orders parts against snake.    Parts come in 15 days later but the snake has
been upgraded to FMC due to scrounging of parts through improper channels.
