A method of transitioning a military vehicle between a plurality of different modes, the method comprising:

• providing a military vehicle comprising a reconfigurable compartment having a floor, a front, a rear, a roof, and sides, wherein the front, the rear, the roof, and the sides are removably coupled with each other to define the reconfigurable compartment and an interior volume of the reconfigurable compartment, the reconfigurable compartment separate from a cab of the military vehicle that provides seating for a driver of the military vehicle, the cab of the military vehicle defined by a plurality of panels that are different from the reconfigurable compartment, an interior volume of the cab at least partially physically separated from the interior volume by at least one physical barrier;
• removing a function-specific one of the floor, the front, the rear, the roof, or the sides, the function-specific one of the floor, the front, the rear, the roof, or the sides having a first structure so that the reconfigurable compartment is a first type of compartment;
• replacing the function-specific one of the floor, the front, the rear, the roof, or the sides with a different function-specific one of the floor, the front, the rear, the roof, or the sides, the different function-specific one of the floor, the front, the rear, the roof, or the sides comprising troop carrier structure to transition the reconfigurable compartment to a second type of compartment, wherein transitioning the reconfigurable compartment between the first type of compartment and the second type of compartment changes an application of the military vehicle, wherein both the first type of compartment and the second type of compartment include the roof that extends a longitudinal length substantially equal to a longitudinal length of one of the sides.
