Learn Military Hand Signals like a Pro

Military Hand and arm signals or what is also called Visual signals were first made by the US Army for field use and are now the most common forms of communication during ops.  Military signals had a recent update from 30 years ago to keep up with needed changes in operations techniques.    

It should be noted that units will also create some of their own signals and civilian Law Enforcement such as SWAT may have their own.  Although they are SOP in the military there is some variation.
