The AK-47
A wounded tank sergeant designs the most widespread gun ever

Tank commander Mikhail Kalashnikov, wounded near Bryansk in 1941, conceived his rifle in hospital, and in 1947 it went to military trials. There are now about 100 million Kalashnikovs in the world, and the AK's outline appears on the flag and emblem of Mozambique.
