In november 19 forty three, the us. Navy launches another line of assault in the pacific war. This one will be an island hopping campaign through the central pacific. The marines initially pile up on the coral beach behind a giant retaining wall that the japanese made out of cut cocoanut trees and cocoanut bushes. But when the japanes starts shooting at you, there's no place to duck, cover and get out of the way. And so they end up chest deep in water on coral reefs, wading with their rifles over their heads, towards teshore.
