Command tunnel vision and the staff’s corrective role

How should tunnel vision be understood in naval command?

It can affect both commander and staff, so a functioning staff must challenge a leader who is overlooking part of the situation.

The Philippine Sea example shows that tunnel vision can affect both commander and staff. Modern operations involve too many simultaneous problems for one person to manage alone. A staff that merely reproduces the commander’s assumptions cannot perform its corrective function. Effective senior staff therefore need the confidence to say when the operational picture is being read too narrowly.
