Between 16th August 1993 and 28th February 1995 the Operation "Testuggine" was carried out by units of the Army.
It provided for monitoring the north-eastern border (the Italian-Slovenian border) to prevent attempts of irregular entry in Italy of people, vehicles and materials.
Firstly, the service was based on a competition in favour of the Ministry of the Interior and it provided for the presence of security forces during the Army patrols.
Since the end of January 1994, after the attribution of the "status" of Public Security Agent, the Units of the Army have operated independently, in coordination with the Police Forces.
On the basis of the directives issued by the Prefects of Udine, Gorizia and Trieste, patrol and monitoring activities have been carried out at night, near the main border crossings that were not controlled by the Public Security Forces, in particular in the areas of Monte Forno to the North and Lazzaretto to the South.
- the section of the border included in the Province of Udine was assigned to the 4th Alpine Army Corps;
- the section of the border included in the Provinces of Gorizia and Trieste was assigned to the 5th Army Corps.
