Well...now I've been in 24 years...and I can tell you THAT isn't true. We complain more than anyone's business!
Sit around the barracks before going out into the field and you will get an earfull...LOL.
LOL, yeah I did forget about barracks talk.
And talk about the chow and discussion as to whether we should attempt to contact the chow, do battle with it, or surrender to it.
[Hint, never surrender to the so called jello.]
What I remember most was doing fire missions.
When we were doing what we were intended to do -blast objects to tiny quivering shreds through application of high explosive- we were in our glory.
Stick us back in the motor pool doing dog and pony show busy work stuff and we did gripe about that.
