In April, the Standschützen units were inspected for the first time. In the wake of this inspection, the Standschützen were divided into those capable of service at the front (thus considered field formations) and those of lower capability (deployed on guarding duties or used as replacements). It was expected that Italy would declare war on Austria-Hungary. For this reason the Standschützen were mobilized on 18 May 1915. Only a day later, the first formations in South Tyrol advanced to the southern front. Another three days later trains arrived at the new front, having crossed the Brenner Pass, carrying North Tyrolese Standschützen. Italy finally declared war on Austria-Hungary on 23 May.
