It concerns troops deployed to Nigeria. In February 2016 the US Government TALKED of deploying a very small number of troops to help the Nigerian army fight Boko Haram.
BUT... ''The deployment WOULD (not there yet) be an advise-and-assist mission and WOULD NOT involve U.S. troops in direct combat with the extremist group''
No patrols.. no night duties.. no fighting.. I think they are training only.
NOW.. NOTICE.. talking of. They aren't there yet.
