A Zaptiè was a colonial Carabiniere (look at own carabinieri patches of the Zaptiè). Here a Zaptiè in a check point few Kms off of Martuba, an important airfield in Cyrenaica. Spring 1941.
The road signs indicate an Italian logistic unit and a 'Staffel Ymer'. Does anybody know this unit?

Fantastic! I like it very much. Note the corazzieri, too.
