I spent 3 days at the Marines' big modern warfare expo. Here's what the service was buzzing about.
I spent three days at the Marines' big annual modern warfare expo in Washington, DC. Drone tech stole the show.
Marines, Pentagon officials, and defense industry executives spoke extensively on panels and in private discussions about the uphill battle of preparing for future warfare, and drones were a hot topic. Marine leaders discussed the difficulties of getting many more drones into the hands of troops and the challenges of adapting to war with these systems.
The Modern Day Marine expo is focused on the innovations Marines need to fight future wars, so it's no surprise that everyone was buzzing about drones this year. These highly versatile machines which can surveil enemies, carry out precision strikes, and more have been redefining contemporary warfare.
Their uses were on display at the "Drone Zone," a section of the expo featuring demos from the Marines' Attack Drone Team. There was also a section devoted to wargaming, another focused on warfighting, and countless booths where companies pitched ideas on what tech Marines might need for future fights.
Game-changing warfare technology
In what was basically a UAS mini-symposium, held in a cluster of quiet rooms in the convention center, about two dozen Marines — from generals to senior enlisted —hashed out what's working and what's not when it comes to drones.
Some expressed concerns about fielding and implementing uncrewed aerial systems within the Corps.
Leaders cited the difficulty of getting drones into the hands of troops due to the slow and complex military acquisition process, as well as tricky procedural and regulatory issues, like deconflicting flight space with the FAA, negotiating on-base training flights for logistics drones, and mitigating risks for civilians on the ground.
I was a little surprised by just how open to reporters like me these intimate panels were and was struck by just how frank Marines were in speaking with me and helping me better understand their challenges.
"We've got to field drones at scale in order to be able to pressurize our training really, to work through some of the real hard problems," said Lt. Gen. Benjamin Watson, who oversees the service's Training and Education Command, during a media event.
He added that he expects the service to receive more drones and loitering munitions, or one-way attack drones,over the next year.
The newly established Attack Drone Team is an important part of the Corps' drive to learn from the war in Ukraine and bring small uncrewed systems into missions. The team demonstrated drone capabilities every few hours at MDM; it will serve as a foundation for competitive teams across bases.
Monday, I observed our Marine Corps Attack Drone Team experimenting with FPV drones. These Marines continue working with industry to deliver an affordable, attritable solution that provides the Fleet the precise mass they need.

Other technology attendees buzzed about at the expo were electronic warfare, virtual training simulators, and the need for quantum communications.
Getting Marines into the fight
Drones are invaluable tools, but they won't be much help if the service can't physically get to conflict zones. That's why an initiative called "3.0 MEU," another timely topic at MDM, is a consistent strategic concern for the Marines' top general.
A MEU, or Marine Expeditionary Unit, is a response force of around 2,200 Marines and sailors who carry out combat missions like amphibious assaults or respond to crises like embassy evacuations.
The Marine Corps term "3.0 MEU" refers to having three groups deployed simultaneously, one from the East Coast, one from the West Coast, and one from a US base in Japan, plus enough ships to have some preparing for deployments, with plans for others to be undergoing intense maintenance cycles.
Long-standing concerns about Navy ship readiness mean that having three groups of three ships deployed with embarked MEUs, with others in training pipelines and maintenance, is really still just a goal for now.
"This is about more than ships, it's about deterrence and denial," Marine Corps Commandant Eric Smith said. "That is why the 3.0 ARG MEU matters; it gives our leaders options." (ARG refers to the naval warship groups known as Amphibious Ready Groups).
The Navy operates and maintains the ships that Marines deploy on. But its fleet has been forced to contend with overwhelming maintenance and repair backlogs. The bedrock of American naval power, the US shipbuilding industry, has been plagued with troubles, too.
With the state of the fleet, there are concerns that it isn't sufficiently prepared for emergencies.
"There's a saying that wars are a come-as-you-are game," said Lt. Gen. Karsten Heckl, the commanding general of Marine Corps Combat Development Command, told Military.com last year on the impact of dismal ship readiness for Marines. "Well, this is where we are. And there is simply no immediate fix."
Taking care of Marines by fixing their housing
Maintaining a mission-ready force requires upkeep of the facilities that troops live in to ensure a certain quality of life.
Renovating barracks, the military equivalent of dormitories, was another important topic at the MDM expo. Barracks across the DoD have deteriorated due to insufficient maintenance, sometimes resulting in mold, water issues, and poor ventilation.
The issue has been exacerbated by decades of war in the Middle East and is one that the lowest, unmarried enlisted ranks deal with regularly.
Now, Marine leaders are trying to boost barracks renovations, which they also hope can help increase force retention. "Barracks 2030" is the Corps' refurbishment answer. But it comes with a steep price tag, nearly $11 billion through 2037.
"The idea is not to fix it and forget it," Lt. Gen. James Adams, Deputy Commandant for Programs and Resources, said of the initiative during a panel on the topic. He added that the service "got ourselves into the position we're in now" by neglecting maintenance.
But funding for Barracks 2030 hinges on Congress, and if lawmakers don't elect to fund the overhaul, it's likely to face painful delays. So it is getting more attention.

How to Take Incredible Underwater Photos Like a Pro Photographer
When you're diving, the water around you filters light — but not evenly. As you descend, red wavelengths disappear first, followed by orange and yellow. Soon, all you have left are greens and blues. Most recreational dives are shallow enough that you'll still be able to capture some oranges and yellows, but after 15 feet or so you have very little red. And that's the best-case scenario, on a sunny day when the water is clear; murky water, cold water, and overcast days all create unique lighting challenges. The result is that your images right out of the camera will typically be far less vibrant than the inspo you've likely seen on social media. If you've been dazzled by underwater photos with vibrant oranges and reds, what you've seen is either the results of a very shallow dive or the product of the photographer's bringing their own lights underwater. Avoid: Color filters Color filters that you mount in front of your camera's lens can serve as a bridge between bringing your own lights and getting enough from the sun. Typically these lights are red, orange, or magenta for underwater use, but they don't add red, orange, or magenta light — instead, they reduce green and blue light. The camera tries to compensate by letting in more light so that there's more red, orange, or magenta than there otherwise would have been. However, I'm not a fan of using these lights, for several reasons. First, doing so darkens the overall image and forces the camera to compensate by increasing the ISO sensitivity, shutter speed, and/or the aperture setting to let in more light; that process tends to reduce overall image quality. In addition, these filters work only at some depths and lighting conditions. So, although filters can help, editing is a better, more flexible fix for beginners. Use: Editing software Virtually all underwater photos you see online have been edited. Generally, they have been brightened, and the colors have been adjusted to make them look a little more natural. Editing is entirely optional, of course, and many of my favorite underwater photos that I've taken haven't been messed with much, if at all. But when you're 50 feet under the sea, the world is blue and green. Editing the images you capture to add reds, oranges, and yellows may make them less 'realistic,' but the result is often more pleasing and interesting to a viewer. Ultimately, there's no right or wrong answer as to how much editing is too much. If you're handy at photo editing, you can use Adobe Photoshop, Lightroom, or Premiere Pro — or any of the many free photo and video alternatives. These four versions of the same image demonstrate how underwater photos can look with different color adjustments. The first is direct from the DJI Osmo Action 5 Pro. The second was edited in the DJI app. The third is the result from AquaColorFix, and the last is my own edit in Photoshop. The first photo is the most 'true to life' in that it's what you actually see when you're underwater. It isn't the most interesting photo, however.

Geoffrey Morrison for NYT Wirecutter In addition, the apps created by action cam manufacturers — such as DJI's Mimo app (iOS, Android via APK only), Insta360's desktop and mobile app (iOS, Android), and GoPro's Quik app (iOS, Android) — have filters to improve the colors of underwater footage from their various cameras. CapCut, our pick for the best third-party video editing app, doesn't have a specific filter for underwater footage but does include the tools you need to fix the colors yourself. But if you don't want to mess with adjustment sliders yourself, consider AquaColorFix (iOS, Android). This automated color-correction app is simple to use and does a great job. It also has traditional image adjustments, as a standard photo editor does. The free version works only with photos and adds watermarks, while the paid version removes the watermarks and also works with video. At this writing, it costs $25 as a one-time purchase, $10 per year, or $3 per month. AquaColorFix makes the colors more visually interesting with just a few taps. There's no singular 'right' way to do photo editing; more elaborate photo editing software, such as Photoshop, will let you do more but at a higher cost in both money and time. Geoffrey Morrison for NYT Wirecutter Another solid option is the Dive+ app (iOS, Android) which has additional social and location-guide features. The free version has a watermark and a limit to how many images and videos you can color-correct per day. The paid version costs $24 per year or $4 per month at this writing. Avoid: LED lights It's possible to add red and orange back into images by bringing your own lighting. You can find rigs that add small LED lights and strobes to everything from action cameras to more elaborate camera setups. But you don't need lights for good underwater photography, and for most people they would be more trouble than they're worth. They add cost and complexity, and even the smallest rigs are bulkier than just the camera itself. Yes, they can absolutely help you get some epic shots, but they're effective only within a short distance from the camera — roughly 3 to 10 feet, give or take a few feet depending on the situation. You shouldn't consider adding lights to your camera before you are extremely comfortable and experienced with both diving and underwater photography.

The Marine Corps' oldest flying squadron flew its last Harrier jump jet flight as the unit's pilots ready to fly new F-35 stealth fighters
The Marines will rebrand a squadron as pilots switch to the F-35B Lightning II. The transition from the AV-8B Harrier to the F-35B is part of modernization. The change is part of service-wide plans to enhance capabilities for modern Pacific warfare. The Marine Corps will soon rebrand a storied aviation squadron as its pilots switch to a new jet designed for next-level warfare. Amid ongoing changes to the Corps, the North Carolina-based Marine Attack Squadron 231 will be renamed "Marine Fighter Attack Squadron 231." The squadron, identified as the service's oldest flying squadron, was formed just after World War I, and it adopted the Harrier jump jet in the mid-1980s. With VMA-231's rebranding, the unit's pilots will no longer fly the AV-8B Harrier, an aircraft known for its short and vertical take-off and landing capabilities. The Corps is doing away with the plane, preferring the new fifth-generation F-35B Lightning II Joint Strike Fighters. Marines fly the stealth jet's B variant built for short runways and big-deck amphibious assault ships. VMA-231, known as the "Ace of Spades," will be deactivated later this year and then reactivated as VMFA-231 in the next fiscal year. The aviation unit completed its last Harrier flight last Thursday at Marine Corps Air Station Cherry Point, according to a news release out Monday. "Everybody knows that VMA-231 is transitioning to F-35s," said the unit's commanding officer, Lt. Col. Paul Truog, stressing that the final Harrier flight was not a "sad day" and asserting that "the Wing, the [Marine Aircraft Group], and the squadron are going to be more capable of responding to any crisis." The Corps has already phased out training for the aviation mechanics responsible for Harrier engine maintenance and for Harrier pilots amid the push to field fifth-generation fighters. In previous discussions with BI, Marine pilots have characterized the newer F-35 as a game-changing capability. The changes come as the Corps remains deep in its transformation, a process to move from fielding a force built to fight counterinsurgencies to one made for modern warfare in the Pacific. It's a shift made all the more difficult by major logistical hurdles in the region and fast changing battlefields being radically shaped by AI and drone technology. Along with the Harrier, the Corps has put F/A-18 Hornets on the chopping block to make way for the F-35. The Hornet made up over half of the Corps' tactical air capabilities in 2022, according to and has been a go-to aircraft for the Marines and the Navy for both offensive and defensive needs. But there's a growing recognition that future fights could demand next-generation capabilities. In its statement on changes to VMA-231, the Marine Corps said "the squadron's transition from the legacy AV-8B Harrier II to the F-35B Lightning II Joint Strike Fighter is representative of 2nd MAW's ongoing modernization efforts to meet the needs of the future fight," referring to the 2nd Marine Air Wing. The Corps' "Force Design" plans, announced in 2020 amid much controversy, has already seen the service scrap its scout sniper program and tanks in an all-out effort to shed any capability deemed less urgent for the Pacific, and it has also rolled out new units in Hawaii and Japan specially formed for fighting along the Pacific's formidable island chains.
