Introduction
If there is a failure in the integrated sight unit (ISU) on the
Bradley fighting vehicle, it will be necessary for the commander and/
or gunner to use the backup sight to view and aim at the target.
Thus, it is important that the line of sight of the backup sight be
aligned with the lines of sight of the weapons on the vehicle.
This task describes the procedures for boresighting the backup sight
on the Bradley fighting vehicle.

Before starting the boresighting
procedures, the following warnings should be noted:
