Externally, the M3 and M2 Bradleys are almost identical; both even featured three periscopes in the rear roof between the ramp and the deck hatch. The side firing ports and their associated periscopes are blanked off on this vehicle, however, revealing it to be the former. The seats for the scouts can be seen in the center of the entryway. (Picture taken 1 Jan 1983 by Steve Catlin; available from the National Archives.)
The interior of the passenger compartment is shown here. TOW missiles are stowed along the right wall, and seats for the two scounts are mounted in the center. The seats fold down so that the man on the vehicle's right sits facing forward, and the man on the left is facing to the rear. The cargo hatch is open, and the three periscopes in the rear roof can just be seen at the top of the image. There is a tunnel to the left of the turret that connects the driver's position with the rear compartment. (Picture taken 20 Apr 1990 by SPC Diana Lindsey; available from the National Archives.)
The right rear of the HMPT-500 transmission is sketched here. Its maximum input torque, speed, and horsepower were 1020 ft-lb, 2600rpm, and 500, respectively. The nominal output torque was 9200 ft-lb, nominal forward speed was 3100rpm, nominal reverse speed was 600rpm, and nominal steering torque per side was 5500 ft-lb. (Picture from TM 9-2520-270-34.)
The lack of side firing ports and presence of periscopes in the rear roof hatch specify this vehicle as an M3A1. The coaxial machine gun is covered by a barrel shroud, and the large trim vane is present on the vehicle's bow. The vehicle commander is on the turret's right side, and the gunner is opposite the commander, behind the armored boxes containing the sights. The TOW missile launcher is stowed on the turret's left side. (Picture taken 8 Jun 1983 by LCPL Contreras; available from the Defense Visual Information Center.)
This vehicle, belonging to 2nd Squadron, 9th Cav Regiment, 3rd Brigade Combat Team, has ERA tiles fitted as well as transparent armor around the commander's position. Note that the headlights have been moved to atop the added armor. (Picture taken 30 May 2006 by SFC Russell Klika; available from the Defense Video & Imagery Distribution System.)
The open ramp access hatch allows us to see one of the scout observers sitting on the folding bench that replaced the earlier folding seats. In contrast to the M2 Bradley, there are no firing ports in the rear ramp. This vehicle also has been fitted with ERA armor boxes on top of its normal spaced armor skirts. (Picture taken 1 Oct 2004 by SSGT Shane A. Cuomo; available from the National Archives.)
The side skirts on this vehicle have been raised, and details of the suspension are visible. The two single and one dual return rollers can be seen, as well as placement of the forward shock absorbers.
The mounting of the coaxial M240C machine gun can be seen in this view. The expended casing chutes for the Bushmaster gun are also visible.
The vehicle's transmission can be seen here. The engine is behind the transmission, to the right of the driver.
The upgraded armor first seen on the M3A2 Bradley replaced the trim vane on the front hull. The spaced armor track skirts are also visible in this head-on view. The coaxial machine gun lacks the barrel shroud present on earlier models. The driver's hatch is open on this vehicle, and the positioning of his four hatch periscopes can be seen. The commander's independent thermal viewer is mounted on the turret's right rear.
The troop compartment hatch is open on this vehicle. The four periscopes common since the M3A1 can be seen in the hatch. The CITV mount is visible on this side of the turret, and mounting points for applique passive or reactive armor are found on the vehicle's side skirts.
The twin TOW missile launcher is seen here raised to the firing position. The plate that covers the front of the launcher falls due to gravity when the device is raised. Details of the diver's hatch and additional turret armor can be seen. The armored flaps for the gunner's sights are also open.
Further details of the erected missile launcher can be seen in this view. The launcher is raised electrically, and has its own elevation mechanism to give a total vertical field of fire of 48°.
The commander's independent thermal viewer is rotated down for stowage here. When in use, this device allows the Bradley commander to search for targets while the gunner is engaging the enemy. An antenna guard is present on the side of the turret, and more details of the periscope placement in the rear hatch are visible.
A better view of the rear hatch with the integral periscopes and the CIV attachment are provided here. Note the applique armor added to the hatch as well.
This view into the troop compartment shows the results of the restowage that was intended to reduce the vehicle's vulnerability. The scouts have a bench along the left of the hull (compared with a front- and rear-facing seat in earlier vehicles). Access to the turret is visible, and the driver's position is accessible from the rear compartment via the tunnel that is formed between the turret and the left side of the hull. Access to floor ammunition stowage is also visible. The turret was segregated by a nonrotating shield with a sliding entry door for the commander and gunner. The turret would not rotate if the door was open, as in this image. Attached to the left side of the turret shield is a flat panel display that can provide passengers with the vehicle's navigational or other information.
A closer view of the scouts' bench seat is presented here. A hose for air filtration is stowed above the seat, two fire extinguishers are on the upper shelf with the filtration masks, and a black clip for an M16 rifle is visible near the front of the shelf. The small tunnel to the driver's compartment can be seen to the front of the vehicle.
A stowage rack for TOW and Javelin antitank missiles is opposite the scouts' bench. Stowage was changed to accomodate the Javelin upon its acceptance, replacing that for the earlier Dragon missile. The label by the black knob reads: "FUEL FILLER COMBAT LOCK. PULL TO LOCK."
The driver's position is illustrated here, looking down into his hatch. The large door to the driver's rear contains gun tools and spare parts, and a pump handle. The large placard on the door to the driver's right contains instructions on starting the vehicle, as well as for swimming and fording water obstacles. The shift pattern is ilustrated on the black shifter housing, and the yellow sticker on this housing gives instructions on the parking brake release method. The switch box placed behind the driver by the turret basket is for fan control. The additional armor protection on the hull is obvious to the right of the hatch.
This blurry shot shows the front of the driver's compartment. The steering yoke is front and center, and the gauge above this is the speedometer. The three indicator lights to the speedometer's right warn the driver of, from top to bottom, unusual transmission oil pressure, high transmission oil temperature, and a clogged fuel filter. The transmission selector is to the right of the steering yoke, and has markings for reverse, pivot, drive, and low gear ranges. The meshed accelerator pedal is placed at the driver's right foot, the green brake pedal is to the left of the accelerator, and there is stowage for a pamphlet bag beside the driver's right leg.
The gunner's instruments and controls are visible in this picture. The gun control cadillacs are in the center of the picture, below the sighting periscope housing. The day sight of the IBAS is on the right, while the gunner's night sight is under the browpad. The black-handled knob to the right of the periscope housings is for opening the protective flaps for the sights and laser rangefinder. As illustrated on the meshed center panel, pivoting the handle down to the vertical position closes the doors. The gunner's seat is visible in the lower left of the picture, and his hatch can be seen in the turret roof.
The Bradley commander sits just to the gunner's right. The turret control box seen on the left of the picture is the same one that was to the right in the picture of the gunner's station above. The screen serves as the commander's thermal viewer, as well as information displays which can be transmitted digitally to or from other units. The commander's override handle is visible on the right side of the turret. The controls below the commander's information screen are for, left to right: stowage of the CITV; adjusting the autotrack feature and gaze size of the IBAS; adjusting the RBD display, and below this selecting whether the laser rangefinder uses the first or last return; and adjusting the mode, polarity, zoom level, etc., of the CITV. Two periscopes can be seen in the turret roof.
