The Inns of Court Regiment

The Inns of Court Regiment (ICR) was a British Army regiment which existed under that name between May 1932 and May 1961. However, the unit traces its lineage back much further, to at least 1584, and its name lives on within 68(Inns of Court & City and Yeomanry) Signal Squadron part of 71 (City of London) Yeomanry Signal Regiment.
