To propel the LAV through water are these externally mounted propellers, one per side.
The main weapon system of the LAV-25 is an M242 25mm Bushmaster chain gun, mounted on a gyroscopically stabilized, hydraulically operated turret with mechanical backup. The turret also holds a pintle-mounted M240G 7.62 fully automatic machine gun as well as smoke grenades.
When filled with the M792 HEI-T (High Explosive Incendiary Tracer) exploding rounds, the 25mm gun is good for a 3,000-meter range with a kill radius of 5 meters. With the tungsten alloy-tipped M791 APDS-T (Armor Piercing Discarding Sabot-Tracer) armor-piercing rounds, the Bushmaster has a range of 2,200 meters and can penetrate up to 2 inches of armor.
We were able to ride in the back of the LAV-25 during target qualifications, and let us tell you, when that big gun goes off, you feel it. The shockwave is strong enough to seemingly take an extra breath for you. It is an amazing piece of weaponry, and seeing the damage it can inflict, we wouldn't want to be anywhere near what the LAV-25 has in its sights. Watching the live fire exercises at night was another treat provided by the Marine Corps. As the teams practiced their night firing, we watched as tracer rounds flew down the range, eventually tumbling skyward as they made direct hit after direct hit. We took some Quicktime movies from our digital camera, and you can find them on www.fourwheeler.com.

With eight-wheel drive and 627 lb-ft of torque, the LAV isn't short on thrust or traction.
Each LAV-25 carries a crew of three: driver, gunner, and vehicle commander, or VC for short. The passenger compartment has accommodations for six Scouts, but typically only four are carried. The VC sits on top of the turret on the right, gunner sits in the turret to the left while the driver is up front.
Smoother and faster than you might think, our LAV-25 was able to charge down tank trails with ease, the LAV-25 feels much lighter than it is and soaks up all but the biggest trail imperfections. It is also amazingly maneuverable, sporting an impressive 51-foot turning radius (for reference, a Jeep Wrangler Unlimited does it in 41 feet, a Dodge Power Wagon in 49-feet). LAVs are designed to cross a trench 81 inches wide, climb a 60-percent grade or traverse a 30-percent slope. In the event of a stuck, they have 15,000-pound winches at the ready.

Just in case: Every LAV-25 is equipped with an onboard 15,000-pound winch and recovery gear.
With credentials like that, it took quite a bit of effort to get an LAV-25 stuck so that C Company could show us their recovery techniques and recovery gear in action. Fortunately, two LAV-25s were able to free themselves without the use of the LAV-R. As much fun as we had taking the LAV-25s out in the field to experience their capabilities, we didn't have a better time than when we were able break bread with the Marines. Whether it was MREs (worlds improved over the surplus rations we used to eat on Boy Scout outings, by the way) for lunch or a mess hall dinner, we enjoyed the conversation and camaraderie with these guys.
As you read this, our friends in the 2nd LAV Division are on tour in Iraq. We won't soon forget our time with these brave men and wish them luck. Please keep these guys in your thoughts and prayers. As of this writing, they are scheduled to be home in May, and if you would like to keep up with C Company, you can find their newsletter at www.lejeune.usmc.mil/2dmardiv/lar/charlie%20company/charliecompany.html
The LAV-R is the support vehicle for the LAV fleet, and as such is outfitted like a well-protected garage, but instead of Pit Bulls and Rottweilers, it has an M240 7.62mm machine gun and smoke grenades. In place of the 25mm Bushmaster chain gun is a 265-degree-capable remote-operated boom crane rated at 9,000 pounds. The recovery variant also carries flood lights, tow bars, giant snatch blocks, an onboard welder, and an awesome 30,000-pound PTO winch. No wonder it weighs a hefty 27,900 pounds. The crew of an LAV-R consists of a VC, driver, and rigger.
At the time we were at Camp Lejeune, all of the LAV-25s were A1 versions. In order to protect our Marines, funding has recently been approved to upfit LAV-25s to the A2 version, which includes an improved armor package, as well as heavier-duty suspension and drivetrain components to support the heavier armor. Part of the upgrades will eventually replace turret hydraulics with an electric-drive motor. An improved thermal site system with laser range finder and engine upgrades are also anticipated in the future.
We'd like to give a special thanks to the Marines of C Company who made for an incredible visit.
