The below photo of a soldier was taken in Sicily in the mid to late 1930’s. I have been told he may have served in Libya for the Italians.
What type of soldier was he and what rank did he have? What job would he have done?
An infantry unit named Acqui operated from 1831 to 1871, again from 1881 to 1926, from 1939 until its massacre by the Germans in 1943, and from 1948 until the present. Most recently, since a reorganization as of October 1, 1976, it has been a motorized brigade.
Through the transformation of warfare and armies the Italians have retained the custom of "naming" the units which are, structurally, the largest homogenous size. This has varied over "Acqui"'s assorted revivals between regiment, battalion, division, to the current brigade structure that matches current NATO unit philosophy.
At a glance, the uniform "feels" more 1940's style to me than either "First World War" style or "post World War Two" style, but I am no expert.
