USMC Maneuver Under Fire Rules: 300-Yard Course & Penalty Seconds
Complete course navigation manual, obstacle sequencing, and official time adjustments for the MANUF event under MCO 6100.13A.
The Maneuver Under Fire (MANUF) is a 300-yard tactical shuttle course combining crawls, casualty evacuation, ammo can carries, and a grenade throw. To max the event with 100 points, male Marines aged 21 to 25 must finish in 2:07 or faster (3:45 minimum pass), while females must finish in 2:42 or faster (4:55 minimum pass). Hitting the grenade target subtracts 5 seconds; missing adds 5 penalty seconds.

Official MANUF Scoring Matrix by Age and Gender
MANUF times are adjusted for grenade accuracy and recorded to the exact second. The table below details passing floors and 100-point maximum ceilings:
| Age Cohort | Male Min Pass (40 Pts) | Male 1st Class Pace (70 Pts) | Male Max (100 Pts) | Female Min Pass (40 Pts) | Female 1st Class Pace (70 Pts) | Female Max (100 Pts) |

Step-by-Step 300-Yard Course Breakdown
The MANUF course is laid out on a 25-yard by 100-yard corridor. Marines navigate seven distinct tactical phases:
- Phase 1: Sprint & Crawls (75 yards). Start in the prone position. On the command "GO", sprint 10 yards, drop into a low crawl for 15 yards (chest and hips close to ground), transition into a high crawl on hands and knees for 15 yards, then sprint 35 yards weaving through cones to the 75-yard turn line.
- Phase 2: Casualty Drag (10 yards). Grab the simulated casualty (a partner within roughly 10 pounds of bodyweight) under the armpits. Drag the casualty backwards through the slalom cones for 10 yards.
- Phase 3: Fireman's Carry (65 yards). Lift the casualty into a regulation fireman's carry over the shoulders. Sprint 65 yards directly across the start line, safely placing the casualty on the ground. Dropping the casualty forcefully results in a penalty.
- Phase 4: Ammo Can Resupply (75 yards). Pick up two 30-pound ammo cans (one in each hand). Sprint 75 yards weaving through cones to the grenade pit at the 75-yard mark. Place the cans on the ground.
- Phase 5: Grenade Throw & Pushups. Pick up the inert practice grenade. From inside the marked throwing box, throw the grenade into the 5-foot circular target located 22.5 yards away. Drop immediately to the ground and complete 3 proper pushups.
- Phase 6: Ammo Can Extraction (75 yards). Pick up the two 30-pound ammo cans and sprint 75 yards in a straight line back through the finish line.
Grenade Accuracy and Rule Penalties
The grenade throw has a dramatic 10-second swing on the Marine's recorded score:
- Target Hit (-5 Seconds): If the grenade impacts inside the 5-foot target circle (or strikes the perimeter marker), the timer officially subtracts 5 seconds from the recorded raw finish time.
- Target Miss (+5 Seconds): If the grenade lands outside the ring, 5 penalty seconds are added to the recorded time.
- Stepping Over Line (+5 Seconds): Stepping outside the throwing box during the throw adds a 5-second boundary penalty.
- Improper Cone Weaving (+5 Seconds): Bypassing a slalom cone on the sprint or ammo can carry incurs a 5-second navigation penalty per missed marker.
The maneuver course follows the lift in the CFT, so check the ammo can lift standards.
