The brigade was formed as the 2nd Brigade during the
1948 Arab-Israeli war when it was split off from the Levanoni Brigade. Named the
Carmeli Brigade because it was led by
Moshe Carmel, the brigade was an
infantry formation operating in northern Israel. It played an important part in
Operation Hiram. After the
IDF was formed, the Carmeli Brigade became its 18th Brigade. During the
Sinai Campaign of 1956, the brigade was stationed along the Jordanian border, in case the Jordanians decided to open a second front, and so was not involved in combat. It was shortly later assigned armoured units to become the 45th Armored Brigade, also known as the "Barak Armored Brigade". It consisted of one tank battalion, two armoured infantry battalions, a mortar battalion and reconnaissance units. The changeover was completed in 1962. During the
Yom Kippur War, it played an important role in defending Israel's border against the Syrian attack in the southern
Golan Heights. 112 soldiers were killed in action, including the brigade commander. The brigade was almost destroyed. The main Syrian attack at 2:30–2:50 PM, confronted by the newly positioned 74th Tank Battalion, under the command of Lt.Col. Yair Nafshi. Nafshi moved his battalion position 1.5 km forward from its previous defensive position, a maneuver that saved his men and machines from the Syrian artillery barrage. His was the only remaining tank force, equipped with 36 Israeli modified
Centurion tanks to fight the Syrians for 3 continuous days until reinforcements and reserves were moved into positions. His battalion was reinforced with a tank company from the 53rd battalion. After 4 days of fighting, his battalion was reduced to 5 operational tanks. More than 102 soldiers and officers died defending the southern Golan Line, from reinforced points (bunkers) 107 to 114. For his gallant, professional, and courageous behaviour during the war, Yair Nafshi received Israel's second-highest decoration, the Medal of Valor. He retired from the army with the rank of Brigadier General. During the battle, Lieutenant
Zvika Greengold, who had arrived unattached to any unit, fought off attacks with his single tank until help arrived. "For the next 20 hours, Zvika Force, as he came to be known on the radio net, fought running battles with Syrian tanks—sometimes alone, sometimes as part of a larger unit, changing tanks half a dozen times as they were knocked out. He was wounded and burned but stayed in action and repeatedly showed up at critical moments from an unexpected direction to change the course of a skirmish. After the war, the task of rebuilding the brigade was assigned in part to
Yonatan Netanyahu who took command of Battalion 71. In the
1982 Lebanon War, it fought in
Beirut and participated in the capture of the local airport. Today, the brigade is part of the 36th Armored Division, the largest regular-service armoured division in the IDF. During
2014 Gaza War, the unit saw deployment in Gaza City. During the
2023 Gaza War, the unit saw deployment in
Bureij. == Brigade organization 2025 ==
