These soldiers must be able to navigate from a departure point to a last known location of an isolated person in order to support a search and rescue or personnel recovery mission. This SMEE is in support of Beyond the Horizon 2012, an annual humanitarian exercise, which will help the Guatemalan and U.S. Army enhance capabilities on personnel recovery, vehicle search, force protection, search and rescue and land navigation.
