The first supplies

The first military vehicle built by Vincenzo Lancia was called the 1Z. It fitted a famous 35 HP engine and was capable of transporting 22 quintals at a speed of 60 km/h. It was 1912 and 1Z was used in the Libyan campaign.
World War I broke out three years later and other two Lancia models, the Jota and the Djota, joined the 1Z for logistic deployment of men, weapons and supplies. Both fitting a 4940 cc - 70 HP engine, the two new models differed by extra carrying capacity (increased to 24 quintals) and different chassis structures: long the first, short the second. Other Lancias were "recruited" during the three years of World War I.
The Theta continued to be built for the military high command, and the chassis structures of the Jota, Djota and 1Z were used for towing artillery, transporting photoelectric cells and as ambulances. An armoured version was outfitted by Ansaldo. Many of these units, especially the Jota, were also adopted by the allied armies.
