Like one of the early entries in the series, this one is set largely in Hawaii, with the main characters resting their between combat assignments. And when they find out they will soon be leaving for New Guinea and more combat... well, they really don't want to go.
Sgt. Butsko is still in the hospital, recovering from wounds suffered in the last book. Without him to keep the platoon in line, half-a-dozen of them get drunk and decide to go AWOL. About two-thirds of the book deals with this--with Lt. Breckenridge risking getting court-martialed himself while he covers for the AWOL men and works to get them back to the platoon. The situation escalates to the regimental commander, but the value of these men as fighters is too large to ignore. Eventually, all are dragged back to duty.
When they get to New Guinea, the story concludes with a long battle-scene as the regiment holds off a Japanese night-attack. Here we get the intense combat scenes that Levinson is so good at--rifles, machine guns, grenades, bayonets and captured samurai swords--along with many, many kicks to the groan--all play a role in the bloody hand-to-hand combat taking palace.
