I apologize for the length of this, but I wanted to find an explanation of the differences between Kaiserjagers, Landesschutzen and Kaiserschutzen because I was confused myself. This combination of three Wikipedia entries gets there. Wikipedia: The Kaiserjäger (officially designated by the Imperial and Royal (k.u.k.) military administration as the Tiroler Jäger-Regimenter or "Tyrolean Rifle Regiments"), were formed in 1895 as four normal infantry regiments within the Common Army of Austria-Hungary. The title Kaiserjäger – literally "emperor's hunters", but meaning "emperor's rifles" – was an honorary nickname and not part of the language of the military chancellery. The unit's official designation was k.u.K. (1.–4.) Tiroler Jägerregiment, i.e. "1st – 4th Imperial and Royal Tyrolean Rifle Regiment". Despite the name "Tirol" in its title its members were not just recruited from the crown land of Tyrol (including Vorarlberg) but also from other parts of the monarchy. The Kaiserjäger were not mountain troops, but regular infantry. These well-trained peacetime soldiers were regularly sacrificed during the campaign in Galicia and could not be replaced to the same extent. In the Gorlice–Tarnów Offensive the 2nd Rifles lost almost 80% killed, wounded and missing - on 2 and 3 May 1915 alone they lost 26 officers and about 600 NCOs and men. The 4th Rifles lost 1,300 men over these two days. In the autumn of 1915, the Kaiserjägerand Landesschützen were transferred to the Italian Front in order to support the despairing Standschützen militia and small numbers of regular forces defending Italian attacks and to assist in stabilizing the front. Austrian Schützen/Kaiserschutzen Tiroler Landesschützen later known as Kaiserschützen. Schützen (En:Shooters) is a German plural noun used to designate a type of military unit of infantrymen, originally armed with a rifled musket and used in a light-infantry or skirmishing role - and hence similar to the Jäger. The individual infantrymen are termed Schütze. The Imperial-Royal Landwehr (k.k. or kaiserlich österreichisch/königlich böhmisch) was the standing army of Austria responsible for the defence of Austria itself. The mountain infantry had the following units: 2 Landwehr mountain infantry regiments (Gebirgsinfanterie-Regimenter), the 4th and 27th 3 Tyrolean rifle regiments (Tiroler Landesschützen Regimenter)—from January 1917 named "imperial rifles" (Kaiserschützen) 1 mounted Tyrolean rifle battalion (Reitende Tiroler Landesschützen) 1 mounted Dalmatian rifle battalion (Reitende Dalmatiner Landesschützen) After 1918, with the fall of the Austro-Hungarian empire, all Kaiserjager and Kaiserschutzen regiments were disbanded.
