“For the first time in eight years, the Department of Defense (DoD) has classified assigned strength data used to measure the development of the Afghan National Defense Security Forces (ANDSF). US Forces-Afghanistan (USFOR-A), the command authority responsible for training the ANDSF, classified its data on Afghan casualties and attrition rates, as well as details on the operational readiness of US-supplied weapons, vehicles and supplies. Coincidentally, or perhaps not, these numbers are generally the most prominent indicators of the issues still plaguing the ANDSF. High casualty and attrition rates, low morale, and poor administrative support systems have been an unfortunate staple of ANDSF development.”
