A HARROWING VIDEO from the Cold War explaining how different types of nerve agents affect the human body has resurfaced this week, as the row between Britain and Russia over the alleged poisoning of ex-Soviet spy Sergei Skripal in Salisbury on Sunday afternoon continues to intensify. Footage from the video, put together by the American armed forces during the early years of the Cold War as an informative film for its recruits, explains the nine symptoms that could result from contact with a nerve agent, including dimness in vision, difficulty breathing and twitching, jerking and staggering. Further clips from the film go on to explain what was known about the three different types of nerve agent available at the time, namely GA, GB and V, before showing a mock-up of a soldier being exposed to the deadly chemicals / mediadrumworld.com
