7.62mm ammunition, and can be operated manually or with electrical

power.

It is gas-operated, lightweight, and air-cooled, and it is

fed by a metallic link belt. The rate of fire is controlled by three

gas regulator settings.

The ISU allows day and night vision for

aiming the coaxial machinegun.

(3) TOW Missile Launcher.

The TOW launcher is located on the

left side of the turret. The launcher tube carries two TOW missiles.

The four major components of the TOW are the integrated sight unit

(ISU), the command guidance electronics (CGE), the power control unit

(PCU), and the TOW launcher.

In addition, there are controls,

displays, and logic and power interfaces.

b. Sighting Devices.

The main sighting device on the Bradley

fighting vehicle is the integrated sight unit (ISU) (refer to figure

1). A backup sight is also provided to be used in the event of ISU

failure.

The vehicle is also equipped with periscopes and support

sights, including a front ring sight, used to aim and fire at low-

flying aircraft and as an emergency sight for ground targets, and a

vane sight used by the commander to quickly align the turret with a

target.

However, only the ISU and backup sight will be discussed

here.
