Infantry divisions were also expected to travel by foot from place to place, with transport vehicles or pack horses used to augment their travel. Divisions evolved over the course of time. For instance, in 1944, Nazi Germany designated some of their infantry formations as "Volksgrenadier" divisions, which were slightly smaller than the regular divisions, with wider issue of sub-machine guns, automatic and anti-tank weapons to reflect the reality that they were to be used in defensive warfare. In 1945, Nazi Germany seconded members of the "Kriegsmarine" to create "naval divisions", which were of lower quality that the infantry divisions of the Army. They also created ""Luftwaffe" field divisions" from members of the "Luftwaffe".
