USMC Base Camp Lejeune Modernizes Tactical Driving

The U.S. Marine Corps is taking a leap forward in tactical vehicle training, trading unnecessary wear and tear for high-tech, immersive realism. With the introduction of the Multi-Platform Driver Simulator, Marines are now able to push the limits of the Joint Light Tactical Vehicle without assuming any physical risk.

According to Shannon Ohlinger, the MPDS training lead and a Marine veteran, the shift in technology is monumental. The new system is designed to build confidence and critical thinking skills at a much faster pace, while conquering the challenges of fuel costs and vehicle maintenance.

"The Operator Driving Simulator used prior to the MPDS was all over the place with training," said Ohlinger. "This entire system is much more advanced than the ODS, and it still has the mobility to mimic the movement of the actual vehicle over different types of terrain."

The MPDS is broken into three distinct parts: the cab itself, made with authentic Oshkosh parts; the situation screen for viewing analytics and a third-person perspective; and the Instructor Workstation (IWS). While not replacing the actual physical training Marines get in a live JLTV or Medium Tactical Vehicle Replacement, it provides a seamless transition from the classroom to the dirt.

"Everything inside the simulator is an exact copy of what you would see in a real-life JLTV," Ohlinger explained. "From the switches and functionality to the smart user interface, startup procedures, and pre-op checks, everything is a one-for-one match."

Where the MPDS truly outperforms previous training methods is at the Instructor Workstation. From this console, instructors can manipulate the environment in real-time, testing a driver’s ability to adapt to sudden, catastrophic changes.

"Through the instructor workstation, I have the ability to throw obstacles at them. I can add rain and thunderstorms, and you will see puddles form, and the mud get slick," Ohlinger said. "You’re going to start having slippage to where operators need to use their CTIS [Central Tire Inflation System], and anything else you would need to incorporate in order to adapt."

Instructors can tailor scenarios to specific unit needs, whether that means deploying a sudden blizzard, initiating low-visibility night driving, or triggering dash warnings like low tire pressure or battery voltage. The goal is to safely overwhelm the driver in a controlled environment, without worrying about the risk of rolling a vehicle or a Marine getting hurt.

For Ohlinger, this capability hits close to home. Having driven over 3,100 miles in Afghanistan, he understands the stakes of tactical driving.

"As a prior enlisted Marine, I can confidently say that if I had training like this, there are situations I experienced that I wouldn’t have ever found myself in,” Ohlinger recalled. "Marines adapt and overcome when they face the unknown, but the MPDS gives them the critical thinking and experience they need ahead of time."

Ultimately, the Marine Corps modernization efforts are about keeping warfighters lethal and safe. The MPDS ensures that by the time a Marine gets behind the wheel of a real JLTV, they have already survived the worst conditions their instructors could throw at them.

"Being in this position gives me the opportunity to help mitigate the accidents that lead to losing service members. I know if I save one life, I have done my job," said Ohlinger.
