The 8th Armored Brigade (Hebrew: חטיבה שמונה, Hativa Shmoneh) was an Israeli mechanized brigade headquartered near Jerusalem. It was the Israel Defense Forces' first armoured brigade which possessed tanks, jeeps and armored personnel carriers (APCs), whereas all other IDF units at the time were entirely infantry-based.
The brigade was called 'armored' for morale reasons, although in reality it only had a single tank company (later in the war, two companies), and a single APC company (these companies became the brigade's armored battalion), and an assault battalion composed of jeeps.
The Brigade's first commander was Yitzhak Sadeh.
The brigade was founded and subordinated to Yitzhak Sadeh on May 24, 1948. Two battalions were created—the 82nd Tank Battalion under Felix Biatus, and the 89th Commando Battalion under Moshe Dayan. Another battalion, the 88th, was founded later.
According to Dayan, the 89th consisted of four companies each made up from different groups: from kibbutz and moshav members, from Tel Aviv, from Lehi, and veterans from South Africa. The battalion consisted entirely of volunteers: "A" company consisted of men from the disbanded Lehi underground organisation; "B" company was taken from the 43rd Battalion, Kiryati Brigade; "C" company from the Golani Brigade. Many of the men joined after personal approaches from Dayan, to the annoyance of their commanding officers. They were stationed at Tel Litvinsky. Their first action was against Irgun members landing arms from the Altalena at Kfar Vitkin, 23 miles north of Tel Aviv. The Alexandroni Brigade was "reluctant" to intervene, and Dayan was unable to deploy ex-members of Irgun from his battalion.
