Hi Kurt,
Troops patroling and securing borders on Southeast Turkey are called Jandarma Ozel Harekat-JOH, units of Gendarmerie Special Operations Command. They are all professional soldiers,not the ones doing their compulsory military service. As all other special units, they use many different uniforms,weapons,vests and backpacks.I created an album and you may check it
here. Please don'hesitate to ask for any questions.
best regards
Engin
