As a brand new Lieutenant I was welcomed to my first battalion by a senior lieutenant named Ed who was getting ready to leave the unit. He had been there three years and was headed back to the states to get promoted and go to Captain School. (It wasn’t really called that, but most of my followers aren’t familiar with the Engineer Officer Advanced Course, and I though Captain School sounded cooler).
Ed was full of wisdom. And since he was older and wiser and I was (as my platoon sergeant so eloquently put it) still wet behind the ears, I listened intently.
He offered advice when I attempted to buy an extra large rucksack. “Why do you need that?” To carry more stuff in the field. “We’re a mechanized unit. You have a vehicle for that.” I know, but we may need to dismount and walk a ways. “If you walk more than 300 yards you should fire your driver.” Ed was good at pointing out the obvious stuff for me.
