As many as 44 Afghan troops go missing while on US military training visits – Pentagon — RT News: 
The Afghan Army has previously been occasionally infiltrated by Taliban militants who carried out attacks on Afghan and US troops. Rogue shootings of foreign troops claimed lives of nearly 40 soldiers in several dozen attacks in 2012.
Before being allowed into the US, Afghans are carefully vetted for security reasons, to make sure they have not been involved in human rights abuses and are not affiliated with militant groups, the Pentagon spokesman said.
