An Army unit originally established to train Afghan forces now has a new mission: teaching U.S. troops how to fight in the jungle. On Tuesday, the 1st Security Forces Assistance Brigade ceased to exist and was reborn as Army Security Cooperation Group – South. The first large influx of soldiers is expected to begin the jungle warfare course in February. The creation of Army Security Cooperation Group – South comes as the U.S. government has shifted its focus to Latin America. That move followed an uproar after a picture leaked online showing a green beret meant to be worn by 1st SFAB soldiers.
