[2] He served in the 71st Brigade as a first lieutenant, which saw action on the Golan Heights as part of the 3rd Armoured Division during the Yom Kippur War.

[3] He attended Bakr University from 1978 to 1980 after the war and graduated with a MA in military science from the Iraqi Staff College during that time.

On 30 June 2002, during a meeting, Hamdani told Saddam Hussein, then-President of Iraq, that war with the United States was imminent.

Although Saddam allowed him to explain for over 45 minutes, some Republican Guard and Ministry of Defense officials did not agree, his strategy was thus not applied in full.

Hamdani protested this and argued that unless reinforcements were rushed to the Karbala gap immediately to prevent a breach, U.S. troops would reach Baghdad within 48 hours.

[7] Hamdani was ordered to launch a counterattack in response to the continued U.S. advance, resulting in a night raid on 2–3 April which was repulsed with heavy casualties.

[10] As of 2009, Hamdani was still in contact with the Iraqi Ba'ath Party, representatives of which had expressed to him their approval for his work to reintegrate former members of the Ba'athist regime into the new Iraq.

Hamdani has claimed however that he only represents former military officials, but that he feels that the government does need to make more concessions to reintegrate former Ba'athists.
