This thesis examines the development of technology and of tactics in the logistics branch. Previous studies discuss a wide range of theories that investigates technology and tactical development for combat units, but it is still unknown how the development of logistics units can be explained. The ambition with this bachelor thesis is to develop a theory that clarifies if the development of the logistics branch’s technology and tactics can be explained with the same theories as for the combat units, or if the process depends on the combat units new requirements that arise from their development. This research is based on a one-case study of the German 1.Panzer division’s combat unit and logistics branch during its active years 1935 to 1945. The analysis is based on Lautenschlägers theory regarding development of technology and tactics. The results comfirm that Lautenschlägers theory explicates the development in the combat units but not in the logistics branch. The results of the analysis instead comfirm that tha logistics brach’s technology and tactics development depends on the combat units and that an independent developing process is absent.
