Realistic, graphic and disturbing war violence. The second half of the film presents dirty, harrowing combat, with lots of blood, exposed entrails and limbs are blown off. Examples are:
A soldier's face is blown off during an air attack. Bloody, graphic and disturbing.
A horse is mortally wounded by an explosion. A gaping hole can be clearly seen in its side. Bloody and very sad.
Whenever someone is shot, blood splatters and we see bodies riddled with bloody, gaping bullet holes. Lots of battle scenes with several soldiers set on fire and screaming in pain; many soldiers are shot multiple times, lots of explosions, one accompanied by a tank being blown up by a mortar.
A soldier mans a machine gun against an amphibious assault: an ensuing explosion rips his arm off. He slowly dies, groaning in pain, and we clearly see the bloody stump while two other soldiers look on in horror. Very bloody and disturbing.
A soldier shoots an enemy soldier with his sidearm and blood splatters. The enemy soldier drops a grenade and it detonates, sending another soldier flying as he is ripped up by shrapnel.
A group of Japanese soldiers commit suicide by holding grenades to their chests. We see the explosions with accompanying blood splatter. A few have their faces blown off and their arms severed. We are then shown their dead bodies afterwards with exposed entrails oozing out of their bodies and viscera sprawled over the floor. Very graphic and disturbing.
A soldier shoots himself in the head with a pistol and we see blood spray out. It splatters onto the face of another onlooking soldier. Very bloody, but brief.
A soldier is set on fire by a flamethrower. He stumbles around, screaming in agony, until he dies a few seconds later.
A main character has an explosion go off in front of him and is rendered blind. We later see his face as he takes off a blindfold, and his appearance (albeit not graphic) may be disturbing to some. He then commits suicide with his rifle off screen.
A soldier's head is shot off from a .50 caliber machine gun. This is very brief and is in the middle of a battle, so is hardly noticeable in the middle of all the chaos. Another soldier is shot multiple times in the chest from a Tommy gun, riddling his chest in a spray of blood. A soldier charges an enemy emplacement with a grenade and is riddled with bullets. Bloody.
One of the main characters gets shrapnel ripped into him throughout his body. Very bloody. He survives until the next morning, after being dragged across the countryside groaning in agony he begs to stop by saying "no more". He then asks his assistant to behead him. In the process of pulling out his sword, the soldier is shot dead. He then pulls out his sidearm and shoots himself in the chest, with accompanying blood splatter.
A soldier is shot in the torso by a sniper, accompanied by a blood splatter and a gaping wound.
Japanese soldiers capture an American and torture him by stabbing him repeatedly with bayonets. He begs for his life as one soldier punches him and then stabs him with his rifle. We see lots of blood as the soldier screams in pain and slowly dies, coughing up blood.
A soldier is shot in the chest and blood splatters. He is taken captive by the enemy and cared for, with very bloody bandages. He later dies.
An American soldier shoots two Japanese prisoners, both of whom hold up their hands in surrender but are shot anyway. Bloody bullet holes.
Lots of off-screen suicides.
A few fist fights.
The entire movie is about war.
