Hyon Yong-Chol, 66, (right) who was named head of North Korea’s military in 2012, was killed in the capital Pyongyang by a ZPU-4 anti-aircraft gun on April 30. The official was last known to have spoken publicly at a security conference in Moscow earlier that month, but is understood to have been arrested shortly afterwards on charges of showing disrespect to Kim Jong-un (left) by falling asleep at a military event and making public complaints about him. It is not the first time anti-aircraft guns have been used for public executions in North Korea, with recently released satellite images showing a number of unidentified people being killed using the brutal method last October. In those executions, the targets were just 100 feet away from the weapons, which have a range of 26,000 feet. See a photo of the anti-aircraft gun after the break
