"This report discusses the results of SIGAR's [ Special Investigator General for Afghanistan Reconstruction] review of Afghan security personnel going Absent Without Leave (AWOL) while training within the United States. The report determines (1) the extent to which Afghan security personnel went AWOL while training in the United States, and why; (2) the processes for vetting and selecting Afghans for training in the United States and for investigating their disappearance once they have gone AWOL; and (3) the impact AWOLs have on the United States and Afghan training and reconstruction efforts. We found that nearly half of all foreign military trainees that went AWOL while training in the United States since 2005 were from Afghanistan (152 of 320). Of the 152 AWOL Afghan trainees, 83 either fled the United States after going AWOL or remain unaccounted for. We also found that these instances of AWOL may have negative consequences, both for Afghanistan and the United States. [...] To help prevent Afghan trainees in the United States from going AWOL in the future, we suggest that Department of Defense (DOD) mentors in Afghanistan work closely with the Ministry of Defense (MOD) and Ministry of Interior (MOI) to develop processes and procedures that increase the likelihood that ANDSF [Afghan National Defense and Security Forces] personnel returning from training in the United States will be placed in positions that take advantage of their newly acquired skills."
