I did the math and Partisan PPSH41's do 25 DPS at close range. That is literally the highest close range DPS on any hand held weapon in the game beside the Ober IR StG 44 which does 25 DPS to.
EDIT: And at Vet 3 when they get 40% more accuracy they have 35 DPS at close range
What is the DPS of commandos in close range for comparisons btw?
