The Carden Loyd Carrier: Designed by Sir John Carden and Captain Vivian Loyd this was a low cost, two-man Machine-Gun Carrier for infantry use. The company was taken over by Vickers-Armstrong in 1927 and the vehicle was mass-produced for the British Army in addition to a thriving export trade. Unpopular with the infantry, they were used mostly by the Royal Tank Corps as embryonic light tanks in the reconnaissance role.
