In 1981, he embarked on a United Nations mission to the volatile region of Cyprus, a commitment that was followed by another overseas assignment in 1988 when he assumed command of a UN battalion in Lebanon. Throughout the 1990s, Hederstedt held various significant roles within the military, including serving as the brigade commander of the Life Guards Brigade, the commander of the Western Army Division, the deputy chief of the operations leadership for international operations, and a military expert at the Ministry of Defence.
