Activated Reserve Marines Rehearse Crisis Response

29 May 2025 | 1st Lt. Brennen Yancey III Marine Expeditionary Force

The ACM rehearsal prepares Marines to respond to scenarios such as combat, humanitarian aid, or disaster relief. ACM rehearsals synchronize aviation, ground, and logistics efforts to rapidly project forces ashore.

“It’s critical that we bring all supporting elements together and ensure they operate together as intended,” said Capt. Luke Doyle-Mason, a Platoon Commander with 2/23. “Stress-testing these procedures is important not only for our own readiness, but also to show our Allies that we can respond quickly to provide assistance in a time of need.”

Within hours of notification, Marines gathered their weapons and gear, convoyed to their assembly area, and executed flyaway drills aboard a CH-53E Super Stallion with Marine Heavy Helicopter Squadron 462. The ACM rehearsal 2/23’s readiness and progress since they attached to 4th Marines as part of the unit deployment program.

“This drill sends a clear message,” said Doyle-Mason. “Regardless of the unit, Marines are trained to successfully execute the mission assigned to them, and our reserve units are just as capable as those on active duty.”
