Amidror was drafted into the Israeli Defense Forces in 1966. He volunteered as a paratrooper in the Paratroopers Brigade. He served as a soldier and a squad leader, and fought in the Gaza Strip during the Six-Day War. He became an infantry officer after completing Officer Candidate School and returned to the Paratroopers Brigade as a platoon leader. Afterwards he transferred to the Military Intelligence Directorate and served in various positions such as a regional brigade Intelligence officer during the War of Attrition, the 162nd Division Intelligence officer during the Yom Kippur War, the Northern Command Intelligence officer, and as the head of the Research Department. Amidror was considered a candidate to lead the Military Intelligence Directorate, but he was passed over after he controversially referred to non-religious Israelis as "Hebrew-speaking gentiles". Instead, he became president of Israel's National Defense College before retiring from his military career in 2002.
