The Essex Yeomanry was a Reserve unit of the British Army that originated in 1797 as local Yeomanry Cavalry Troops in Essex. Reformed after the experience gained in the Second Boer War, it saw active service as cavalry in World War I and as artillery in World War II. Its lineage is maintained by 36 (Essex Yeomanry) Signal Squadron, part of 71 (Yeomanry) Signal Regiment, Royal Corps of Signals.
