#20 Omar al-Shishani (aka “Omar the Chechen”)
Of all the ISIS leaders killed in action, he is perhaps the most well known. He was widely considered to be the terror group’s minister of war. Al-Shishani was killed as a result of an American airstrike in March 2016, near the Syrian border city of Shadadi. He survived the initial strike but later died of his wounds. It’s widely thought that al-Shishani is referred to as “the Chechen” because of his physical appearance, though he is in fact from Georgia.
Shishani also headed the terror group’s main prison in Raqqa, Syria. The U.S. State Department once offered $5 million for information leading to the capture of Shishani. Shishani was also called “Abu Meat” by detractors because he had a reputation of staying in the rear with the gear while ordering others into battle.
