The Scottish Horse Field Ambulance developed an operating car, designed by Colonel H. Wade in 1914, which enclosed an operating table, sterilisers, full kit of instruments and surgical equipment, wire netting, rope, axes and electric lighting in a Wolseley chassis. The car was used during the Gallipoli Campaign at Suvla, in the Libyan Desert (during the Senussi Campaign), and at Qantara in Egypt before being attached to the Desert Mounted Corps Operating Unit in 1917. Subsequently taking part in the Southern Palestine Offensive, which culminated in the Capture of Jerusalem.

On 17 August 1915, the brigade boarded SS Transylvania at Devonport and sailed to Gallipoli where it landed at Suvla on 2 September. It joined 2nd Mounted Division and remained with it until evacuated on the night of 19/20 December 1915. It left 2nd Mounted Division on 22 December. It was transported to Alexandria via Imbros (20-24 December), arriving on 28 December and went to Sidi Bishr Camp.

In February 1916, the Scottish Horse Mounted Brigade was absorbed into the 1st Dismounted Brigade (along with the Lowland Mounted Brigade ) under the command of the 52nd (Lowland) Division to defend the Suez Canal. Br-Gen Marquis of Tullibardine was assigned to command the new dismounted brigade.
