"The Vietnamese Unit Commanders and US Advisers who participated in the evaluation consider the AR-15 Rifle to be a more desirable weapon for use in Vietnam than the M1 Rifle, BAR [Browning Automatic Rifle], Thompson Sub-Machine Gun, and M1 Carbine for the following reasons: (a) It is easier to train the Vietnamese troops to use the AR-15 than the M1 Rifle, BAR, M1 Carbine, or the Sub-Machine Gun. (b) The AR-15's physical characteristics are well suited to the small stature of the Vietnamese soldier (see photographs I and 2, Annex 17). (c) It is easier to maintain the AR-15 both in the field and in garrison than the M1 Rifle, BAR, Sub-Machine Gun, or the M1 Carbine. (d) The ruggedness and durability of the AR-15 are comparable to that of the M1 Rifle and superior to that of the BAR, SubMachine Gun, and M1 Carbine. (e) The AR-15 imposes less logistical burden than any of the four principal weapons presently being used by Vietnamese Forces. (f) The AR-15 is tactically more versatile than any present weapon being used by Vietnamese Forces. (g) In semi-automatic fire, the accuracy of the AR-15 is considered comparable to that of the M1 Rifle, and superior to that of the M1 Carbine. (h) In automatic fire, the accuracy of the AR-15 is considered comparable to the Browning Automatic Rifle and superior to the Sub-Machine Gun."
