Question: What is the name of the Austro-Hungarian general and historian from the province straddling the southern border of the Habsburg Monarchy?

full_context: Document 1: Kingdom of Slavonia: The Kingdom of Slavonia (Croatian: "Kraljevina Slavonija" ; German: "Königreich Slawonien" ; Latin: "Regnum Sclavoniae" ; Hungarian: "Szlavón Királyság" ) was a province of the Habsburg Monarchy and the Austrian Empire that existed from 1699 to 1868. The province included northern parts of present-day regions of Slavonia (today in Croatia) and Syrmia (today in Serbia and Croatia). The southern parts of these regions were part of the Slavonian Military Frontier, which was a section of the Military Frontier.
Document 2: Roman military frontiers and fortifications: Roman military borders and fortifications were part of a grand strategy of territorial defense in the Roman Empire, although this is a matter of debate. By the early 2nd century, the Roman Empire had reached the peak of its territorial expansion and rather than constantly expanding their borders as earlier in the Empire and Republic, the Romans solidified their position by fortifying their strategic position with a series of fortifications and established lines of defense. Historian Adrian Goldsworthy argues that the Romans had reached the natural limits which their military traditions afforded them conquest over and that beyond the borders of the early-to-mid Empire lay peoples whose military traditions made them militarily unconquerable, despite many Roman battle victories. In particular, Goldsworthy argues that the cavalry-based warfare of the Parthians, Sarmatians and Persians presented a major challenge to the expansion of Rome's infantry-based armies.
Document 3: Varaždin Generalate: The Varaždin Generalate (German: "Warasdiner Generalat" , Croatian: "Varaždinski generalat" ), also known as the "Windische Grenze" ("Wendian/Wendish [Slavic] Border") in German, was a Habsburg Monarchy Military Frontier province centred in Warasdin (Varaždin), Kingdom of Croatia within Habsburg Monarchy, that existed between 1531 and the 18th century.
Document 4: Emil Leeb: Emil Leeb (17 June 1881 – 8 September 1969) was a Bavarian-German general who saw active service during both World Wars. His older brother, who became Field Marshal Wilhelm Ritter von Leeb, had the knightly rank of "Ritter" and the nobiliary particle of "von", not by birth, but thanks to the conferment of the Bavarian Military Order of Max Joseph and a patent of nobility. Hence, the older brother had “von” between his names, but the younger brother did not.
Document 5: Austria-Hungary: Austria-Hungary, often referred to as the Austro-Hungarian Empire or the Dual Monarchy in English-language sources, was a constitutional union of the Austrian Empire (the Kingdoms and Lands Represented in the Imperial Council, or "Cisleithania") and the Kingdom of Hungary (Lands of the Crown of Saint Stephen or "Transleithania") that existed from 1867 to 1918, when it collapsed as a result of defeat in World War I. The union was a result of the Austro-Hungarian Compromise of 1867 and came into existence on 30 March 1867. Austria-Hungary consisted of two monarchies (Austria and Hungary), and one autonomous region: the Kingdom of Croatia-Slavonia under the Hungarian crown, which negotiated the Croatian–Hungarian Settlement ("Nagodba") in 1868. It was ruled by the House of Habsburg, and constituted the last phase in the constitutional evolution of the Habsburg Monarchy. Following the 1867 reforms, the Austrian and the Hungarian states were co-equal. Foreign affairs and the military came under joint oversight, but all other governmental faculties were divided between respective states.

He commanded a Serb Hussar Regiment consisting of the colonists he brought to Russia. After Šević's death, Slavo-Serbia was disestablished, and many of his descendants became notable military officers in the Russian Imperial Army. Over time, all the Serb colonists became assimilated.
