Introduction
Another element of the Bradley fighting vehicle fire control system
which must be boresighted is the integrated sight unit (ISU).
The
ISU is the primary sighting device of the vehicle. The night sight
of the ISU must be boresighted to the day sight to ensure accuracy
during aiming and firing in daylight and at night.
This task
describes the two methods of boresighting the ISU night sight to day

There are two methods of boresighting the night sight to day sight.
The convenient target method should be used when visibility is good
