The toylike appearance of the M24 is deceiving; this was the most heavily-armed light tank of the Second World War. The large steering assembly access hatch is apparent in the hull front, and the torsion bar suspension was a first for American light tanks. The opening in the underside of the gun shield to the 75mm gun's right is for the coaxial machine gun; the gunner's telescope was mounted on the opposite side of the 75mm gun. The tracks on this tank are the T85E1 double-pin type.

The commander's sighting vane visible in the image above is highlighted here. This allowed the commander to quickly slew the turret onto a target and decrease engagement times. The aperture for the gunner's periscope is in the hull roof in the foreground, and a spotlight is intruding into the image from the upper right.
The rear of the vehicle and its stowage is shown in this picture. (Picture from TM 9-729 Light Tank M24.)
The top of the tank is seen in this picture. Not labeled is the aperture for the smoke mortar, which is visible in the turret roof in front of the loader's position. (Picture from TM 9-729 Light Tank M24.)
The innards of the tank are diagrammed in this sketch. (Picture from TM 9-1729C Ordnance Maintenance--Light Tank M24 and 155-mm Howitzer Motor Carriage M41 Tracks, Suspension, Hull and Turret.)
The driver's controls are detailed here. The driver and assistant driver each had a set of pedals and levers (although the assistant driver lacked knobs on the steering lever ends to activate the parking brakes). The transmission range selector lever allowed the driver to select neutral, drive, or low range. This lever did not shift gears, but positioned the valves in the transmission control mechanism for the appropriate range. Low range allowed shifting through first and second speeds to take advantage of engine braking. The transfer unit shift control lever had positions for neutral, high and low ranges, and reverse. The accelerator pedal controlled both engines, and the neutral pedal allowed the driver to temporarily throw the tank into neutral without moving the transmission range selector. Releasing the pedal returned the transmissions to the selected lever position. Even though the transmissions were automatic, switching the transfer unit shift control between ranges required them to be in neutral, and the neutral pedal allowed the driver to do this without shifting the transmission range selector into neutral.

This turret interior view showcases the gunner's controls. To activate the gun's vertical stabilizer, the gunner would move the elevating shifter lever to the right. That lever removed the elevating arc and pinion gear from mesh and activated the disengaged switch contacts. The gunner was provided with rheostats to adjust the stiffness of the stabilizer's vertical resistance as well as resistance during recoil. Both of these could be adjusted on the fly as conditions dictated. (Picture from TM 9-729 Light Tank M24.)
