for the technical training of infantry pioneers

This article is largely based on the research of Oswald Mederle, which in detail under
The Klausen-Villnöß barrier 1914-1915 and Pioneers in Teis can be found.

From January 1915, the construction of the new positions around Teis was used for several weeks. Instruction courses for posture construction to hold. Explosives, emergency bridge construction and field fortification are taught and practiced. The pioneers trained here were to apply the acquired knowledge in the field and fortress war and also pass it on within the tribal troops. The k.u.k. military command in Innsbruck has the following:

The military command has (...) seen with satisfaction that the greatest attention has been paid to technical training on all sides and that the training results achieved fully correspond. The officers trained in the instruction courses are now responsible for the technical training of the entire crew in the simplest technical operations and in the skillful handling of the long-stemmed tools. In the future, it is desirable that there are 8 trained pioneers per company. (....)

Visits for teaching purposes
The training positions in Teis were inspected by interested visitors from the near and far surroundings and used for teaching purposes. Thus we read in the diary of the k.k. Standschützen-Bataillon Bolzano:

2 March 1915
Several officers, furthermore batches and crews of the pioneering department go to visit the field fortifications in Theis near Klausen.

21 March 1915
There is a second visit to the field fortifications in Theis, involving several officers and stand shooters of the battalion.

This is the last training course in Teis that we are aware of. However, we know from the records of Oberleutnant der Reserve Franz Ortner and his entry of

10 May 1915:
Departure 6.30 am through the Villnössertal. Here, solid work is carried out and concreted everywhere in order to complete trenches and gun stands. The war with Italy will be inevitable...

With Italy's declaration of war against Austria-Hungary on 23 May 1915, the period of training was over. Now every force was needed to hold the positions on the new front. The theory had to make way for practice...
The equipment: Tools and explosives

Pioneers and sappeurs (from the Italian "zappa" i.e. hoe) were responsible for the technical work of the fortress war: Construction of field fortifications, spanning, emergency bridges and bridges, roads and telegraph construction, repair work, explosives... They also had to pave the way for the troops by clearing away obstacles. The necessary tools (‘bullet’) were delivered by means of carts and, if necessary, carried on site by the soldiers in trays on their bodies.

On 17 February 1915, the k.u.k. Militärkommando Innsbruck ordered the k.u.k. Gruppenkommando Bolzano to reposition the Tyrolean ski jumping columns. The supplements to this arrangement provide information about the equipment and thus about the equipment with which a Sappeur had to learn to deal:

The Sappeur officers Not only had to be proficient in all fields of engineering and its practical applications to war technology, but also improvisational talent and quick comprehension were indispensable for a Sappeur officer.
