I found ironing a necessary tool for me while in the Army. Came in handy.
Yes, I remember at our very first few pre-deployment briefings, how Army officers recommended that I bring a portable iron with me on my first deployment to Bosnia in the mid 1990s.
Actually, I was astounded, - this would not have been on my list of things to bring - but they stressed that one had to 'look smart and professional' even though we were working in a country that had been wracked and wrecked by war.
