In the immediate aftermath of the war division slices stood at around 13,000–15,000 for the Soviet forces (with combat divisions of 9,000–12,000 men) and around 40,000 for Western forces (with combat divisions of 16,000–18,000 men). By 1950 the US division slice stood at around 35,000, though this increased significantly to around 50,000 men if a division were deployed from home (as for example US forces were in the Second World War). Much of the increase in troop numbers was driven by a 33% increase in the number of combat troops in a division, only 25% of the slice was made up of troops from the zone of the interior. By 1950 the worldwide division slice for US troops was around 80,000, and the Korean theatre division slice was 35,800; this compared to a Soviet division slice of 20,000 for 1960.
