Förhållandet mellan teknik och taktik är svårt att fastställa. Klart är dock att de påverkar varandra. Uppsatsen syftar till att pröva Öhrns teori om förhållandet mellan ny teknik och taktikutvecklingen, som består av tre slutsatser som skall uppfyllas för att gynnsamma förutsättningar för taktikutveckling ska äga rum. Prövandet genomfördes genom att ställa teorin mot införandet av Stridsfordon 90 i svenska armén som slutfördes under 1990-talet. Genom att skapa hypoteser baserat på Öhrns teori har stridsfordonets roll som tekniksystem på kompani- och bataljonsnivå i svenska armén undersökts. Studien resulterade i att Öhrns teori i hög grad var tillämpbar på det valda markfallet. Stridsfordon 90 kunde konstateras vara ett för kompaniet större tekniksystem och hade en taktik som anpassats för sina speciella förmågor, kombinerat med att organisationen, Försvarsmakten, hade förutsättningar att genomföra en medveten taktikutveckling. På bataljonsnivå  kunde inte stridsfordonet klassificeras som ett större tekniksystem i förhållande till bataljonens andra tekniksystem och en märkbar taktikförändring kunde heller inte kopplas till dess införande, vilket är i enlighet med teorins resonemang. Det föreslogs att teorin specificerades i en av sina tre slutsatser för att tydliggöra att större tekniksystem är relativt i förhållande till förbandsnivå. / The connection between technology and tactics is hard to define. Although it is clear that they affect each other. The aim of this stydy is to try Öhrn’s theory about the connection between new technology and tactical development, which consists of three conclusions that must be fulfilled for favourable conditions of tactical development to exist. The trying of the theory was executed by applying it on the introduction of Stridsfordon 90 (Combat Vehicle 90) in the Swedish army that concluded in the 1990’s. By making hypotheses based on Öhrn’s theory the combat vehicle’s role as a technical system at company and battalion level in the Swedish army has been researched. The study resulted in the conclusion that Öhrn’s theory was highly applicable on the chosen case. Stridsfordon 90 was found to be a larger technical system and it used tactics adapted for its special abilities, combined with the fact that the organisation, the Swedish Armed Forces, had prerequisites for conducting an intentional development of tactics. At battalion level the combat vehicle could not be found to be a larger technical system in relation to the battalion’s other technical systems and a noticeable tactical evolvement could not be connected to its introduction, which is in accordance with the theory. It was suggested that the theory was specified in one of its conclusions to clarify that a larger technical system is relative to the unit level.

Theorists in war studies have since the 1940’s debated the issue of the connection between technology and tactical development, and at the end of the 1990’s a technological revolution in warfare was debated. As presented in this thesis the debate is far from completed. Lieutenant Commander Erik Öhrn made an effort to construct a general theory for this connection in 2011 at the Swedish Defense University. Preliminary studies prove that the theory is applicable for naval tactics. The purpose of this thesis is to examine if the theory is valid in mechanized tactics by studying the introduction of the Swedish Combat Vehicle 90. In using a qualitative method, searching for theoretical constructed indicators, this thesis finds shortages in the theory as a general theory for the connection between technology and tactical development. The definition and concept of technology is among these shortages, which is a crucial part of the understanding of the revolution debated in previous research.

The aim for this thesis was to investigate how boys and men are portrayed in contemporary Swedish literature that have been acknowledged for depicting male violence. This is done through a comparative analysis of Björnstad (2016) by Fredrik Backman and Jävla karlar (2023) by Andrev Walden. The study is motivated against the notion that boys in children’s literature, as well as within the field for masculinity theory, historically have been portrayed as having contrasting characteristics in relation to men. Boys are created as wild whereas men are portrayed as civilized controlled beings, holding the ideal the boys should aspire to reach for. Sara Ahmed’s theoretical concept stickiness is used to explain how the image of the boy discursively is constructed as subordinate in relation to the man. In addition to this, a methodological model is developed, consisting of three new chronotopes: the boyroom and the man-land, connected by the teenage-guy’s vestibule. The teenage-guy’s vestibule is a development of Michail Bachtin’s threshold-chronotope, and is used as the viewpoint in the analysis. The boy-room is a development of Magnus Öhrn’s chronotope the boy land (pojklandet), which have been used to analyze boys in historical children’s literature. Through the analysis it becomes visible that the ideal for boys as well as men is still constructed from a patriarchal structure. Boys are raised according to the ideal of the wild boy, reproducing the idea that male subjects are inherently wild, which is seen as a discursive construction that allows for male violence to continue. Both novels also work to contest this notion by addressing that the wild characteristics originate and belong in the man-land. The comparison shows that more literary representations of boys as well as men could work to counteract the hierarchy, and thus the idea that masculinity is connected to control and domination.
