The USMC M16A2/A4 and M4 carbine marksmanship program consists of two tables. Table 1 course of fire:
200m: Slow fire: 5 rnds standing, 5 rnds kneeling, 5 rnds standing in 20 minutes; Rapid fire: 10 rnds in 1 magazine going from a standing position to a kneeling position in 60 seconds (This is a recent change)
300m: Slow fire: 5 rnds kneeling; 10 rnds in 1 magazine going from a standing to a prone position in 60 seconds (This is a recent change)
500m: Slow fire: 10 rnds prone in 10 minutes
During table two, Marines will shoot from the 25- and 50-yard lines with a flack jacket and Kevlar. Marines must hit 75 percent of their rounds at 25 yards and 50 percent at 50 yards to qualify. For the full course of fire you can check out the MarAdmin
here. Table 2 has radically changed in the last few years. Originally, Table 2 or "Field Firing" was considered a joke as it was not scored and the exercises were not taken seriously (and shooting in a gas mask sucked...) The new course emphasizes rapid acquisition of the target with multiple rounds placed on target in a quick manner. Much more relevant.
Active duty Marines must shoot both tables annually. Reserve Marines shoot Table 1 on even years and Table 2 on odd years.
