Adam's military career began in 1976 when he joined the Israeli Armor Corps. Before becoming the Aluf in charge of the Northern Command in 2005, he was the Director of the Israeli Technological and Logistics Directorate. As head of the Northern Command, Adam led and coordinated Israeli forces against Hezbollah during the 2006 Israel-Lebanon conflict. On August 8, 2006, IDF Deputy Chief of Staff Moshe Kaplinsky was surprisingly appointed to the Northern Command as a special representative of the Chief of Staff in response to criticism by the government over the Command's handling of the conflict. Adam announced his resignation on September 13, amid continuing criticism of the war's conduct.
