Thank you for the information! I like to create historical recreations from books, manuals and articles. I find this educational. For example, moving into FFP at night with FLIR, digging in with an initial hide providing cover as well as concealment. I have not seen this done in any YouTube including those created by professed veterans. I have only seen one YouTube where countermeasures are mentioned such as claymores. I would recommend Arma 3 enthusiasts check out Major John Plaster's web http://www.ultimatesniper.com
