ZERO SIGHTS (PERFORM INITIAL ZERO)
NOTE
This procedure is for establishing initial zero. Once an accurate zero has been established and recorded for each sight,
it is unnecessary to repeat initial zeroing unless:
Gun tube is changed.
Gun sight linkage is moved.
All sights are removed at once.
To zero sight that has been removed or replaced, go to page 2-447. Zeroing requires all four crewmembers at their stations.
Title of crewmember before steps (example, Commander:) will be crewmember that does steps underneath.
For more information on zeroing, see chapter 4 of FM 17-12.
