1. Situation

From 14–18 February 2026, 2d Battalion, 7th Marines executed a battalion-level live-fire training package on Range 400 Series, Marine Corps Air Ground Combat Center, Twentynine Palms. The package included individual qualification, squad attacks, and a culminating platoon-level live-fire and movement exercise. The training supported the battalion's pre-deployment training plan and addressed the deficiencies identified in the previous quarter's commander's training assessment.

2. Mission

The battalion conducted progressive live-fire training in order to validate squad and platoon proficiency in the offensive scheme of manoeuvre and to certify the rifle companies for subsequent combined-arms training.

3. Execution

All three rifle companies cycled through the range package over the five-day evolution. A total of 412 Marines participated. Individual marksmanship qualification yielded a 98.7% qualification rate, the highest in the regiment for this fiscal year. Squad attacks were executed without a Class A or Class B mishap, the first time in five years that a battalion-level package on Range 400 has been completed mishap-free. Range Safety Officers reported zero negligent discharges across all 412 participants.

Logistical support was provided primarily by the Battalion S-4 cell, which coordinated ammunition draw, transportation, and chow forward. Communications support, including the establishment of the range tactical net and the casualty-evacuation net, was coordinated by the Battalion S-6 and executed by the S-4 communications detachment.

4. Sustain

• Battalion-level pre-execution rehearsals at the company command post drove down friction on the first day of execution.
• Forward-positioned medical support shortened MEDEVAC rehearsal times.
• Detailed range-control coordination prior to execution prevented schedule slippage on Day 3.

5. Improve / Recommendations

• Battalion-level pre-execution rehearsals should continue to drive down friction on the first day of execution.
• Forward-positioned medical support should be retained to shorten MEDEVAC rehearsal times.
• Detailed range-control coordination should remain a priority to prevent schedule slippage.
