Does this upset anyone?

I have seen some things during my service that defied all reason. I do not know to this day why some things are allowed to "slide" and others are not. Sometimes, the word "fair and just" is completely absent. Example: A SFC with 17 years of service was over-weight. He was a great leader, all of the junior enlisted admired him, and he truly cared about his troops. Somebody decided after all that time he should lose a LOT of weight, or get kicked out. He was told to lose a impossible amount of weight in a very short time. He never had a chance...and after almost making retirement, was given the boot. In this very same unit, there was a E-5 who was a chronic and severe alcoholic. He went up and down in rank like a yo-yo. He was not kicked out. I asked my XO, off the record about the comparison, and his reply to me was, "The army got the job done with Sgt ****. He will retire as a E-5, maybe less. With the health problems he has, he won't be drawing retirment for very long, he will be dead. The army gets the better end of the deal". The reply is so outlandish, I could not have possibly made this one up. Go figure. It is what it is.
