ancestral sign-reading

AN elite group of Native American trackers is joining the hunt for terrorists crossing Afghanistan's borders.

The unit, the Shadow Wolves, was recruited from several tribes, including the Navajo, Sioux, Lakota and Apache. It is being sent to Tajikistan and Uzbekistan to pass on ancestral sign-reading skills to local border units.

In recent years, members of the Shadow Wolves have mainly tracked smugglers along the US border with Mexico.
