Crossley 25/30 hp Tenders were utilised by the British Army in Ireland from 1919 until their withdrawal in 1922. The Irish Army continued to use them for troop transport throughout the Civil War period, but they were worked hard and appeared to have received little care: of 454 originally supplied, only 57 were in service by 1926 with a further 66 being overhauled or repaired. The 20/25 model was also the first vehicle to be supplied to London's Metropolitan Police Flying Squad in 1920, some of which were fitted with radio equipment.
