What was significant about the Battle of Tarawa in relation to amphibious doctrine?

The significance of the Battle of Tarawa in relation to amphibious doctrine lies primarily in the challenges faced during the landing operations. The requirement for Marine forces to wade approximately 500 yards to shore due to the tide is a critical point. This event highlighted the issues of pre-assault reconnaissance, tide considerations, and the limitations of existing amphibious assault tactics.

The extensive distance that Marines had to wade under enemy fire exemplified the need for improved planning and execution of amphibious assaults, leading to changes in how future operations were conducted. The lessons learned from the challenges at Tarawa significantly influenced the development of amphibious warfare doctrine, emphasizing the necessity for better landing craft, approach timing, and extensive preparation to mitigate risks in future operations.

This battle underscored the importance of coordination and understanding the operational environment in accomplishing successful landings in hostile territory.
