I did one hitch in the Marines. When I checked into my unit out of boot some guys just got back from the float where they evacuated Saigon. Although radio code was my lowest test score they made me a radio operator in a tank battalion; I guess the Practical Joke Department that Heinlein described was working overtime :^) As much as I liked it, I extended to check out my re-enlistment options, it's been hard to describe to people the contrasts that one experiences in the military. Things like having to carry out mindless orders in numbing detail in some cases, and yet being given free reign to tackle difficult problems in other cases. Another was having to police an area (pick up every tiny piece of paper) over and over, and yet being able to leave large piles of twisted, smoking metal all over other areas :^) We spent a lot of time carrying, drilling with, cleaning, and shooting rifles, and I enjoyed shooting on a military range.
