A captain of a battleship

Sits in the control room when suddenly one of his officers comes in.
"Sir, there is a ship attacking us from the east."
The captain looks up from his controls and says,
"Bring me my red shirt"
So the officer brings the captain his red shirt and the crew is able to subside the attacking ship. The next day the captain is sitting in the control room again when the same officer comes in and states,
"Sir, there is a ship attacking us from the north"
The captain again says,
"Bring me my red shirt"
This time the officer asks,
"Sir, why do you wear this red shirt while we are fighting battles?"
The captain replies,
"I wear it so in battle when I start to bleed none of the crew can see my wounds and get discouraged from fighting."
The officer accepts the answer and grabs the captain's red shirt, and the crew fights off the attacking ship. The next day when the officer came into the control room to speak to the captain he stated,
"Sir, there are ships attacking us from the north, south, east, and west."
Hearing this, the captain stood up and spoke firmly,
"Bring me my brown pants."
