I re-watched Jack Reacher last night and have a few questions regarding the tactics used in the finale. Yup, I'm aware that it is only a Hollywood movie but I've read that the director drafted in former US SEALS to advise on the sniping and weapons handling like he did on Way of the Gun so I'm interested to know if something I saw would ever be done on ops or trained. If you've not seen the film dont read on as they'll be spoilers. In the finale Tom Cruise and a retired USMC gunny played by Robert Duvall are told to go to a quarry and they know it's an ambush so do a quick recce and decide that there'll be a sharpshooter in high ground under some floodlights and spot another couple of shooters milling about at the base of the quarry. Duvall keeps his dominant eye closed during these scenes to perserve his night vision and it's decided that Cruise will drive into the quarry to draw fire while Duvall spots muzzle flashes and hopefully pick off the shooters. However when Cruise drives into the quarry and it goes noisy Duvall stays in cover with both eyes shut and seems to try to pinpoint the shooters positions by listening for the shots being fired. So my questions are - Is this Hollywood silliness or has this ever been done? Duvall's character would be of the South East Asia generation so would it be something he'd have done to identify firing positions in dense foliage? Is there any examples of snipers engaging targets using sound alone to identify enemy positions? Bit daft I know but it just pricked my curiosity so any answers welcome. Over to you my internet amigos.
