The 11th Brigade (also known as the Yiftach Brigade) is a reserve unit in the Israel Defense force, composed mainly of fighters who completed their service in the Unit 621 – 'Egoz'.

In the 1948 Arab–Israeli War it was a Palmach infantry brigade. It was formed in late April 1948 from existing Palmach battalions: the First Battalion, that resided in Jezreel Valley and the Third Battalion in the eastern valleys. In late 1948, the Second Palmach Battalion was transferred to it from the Negev Brigade.^[1]

The Palmach memorial website records 274 of its members being killed whilst in the Yiftach Brigade.^{[citation needed]}

In May 1949 the Palmach brigade was disbanded. This was part of a general downsizing of the IDF (9 out of 12 brigades were disbanded). It was also considered by many as part of Ben-Gurion's process of disbanding the Palmach itself.^[2]

A while after that, it was re-established as a reserve unit that served in the Gaza Strip front^[3][4] As an infantry brigade it also fought in the Suez Crisis and in the Six-Day War in the Gaza Strip^[4][3]

In 1971 the brigade was converted to an armored brigade. It fought in the Egyptian front of the Yom Kippur War in 1973. After the war it was regrouped and its unit number was changed to 576. in 2006 the brigade fought in Operation Defensive Shield.^[3]

In May 2014 it was disbanded. ^[3]

In 2016, it was decided to reestablish the brigade as an elite infantry brigade in the reserves, called the "Reserve Commando Brigade", based on the reserve battalions of the 810th Brigade 'Hermon', which was closed as part of the multi-year Gideon plan. Most of the soldiers off the brigade completed their service in the Egoz unit. In September 2020, the brigade transferred command to the 99th Infantry Division (Reserve), where it serves as a commando reserve force.
