The battle scenes are very graphic, realistic, and absolutely spine chilling to watch. They are long, and filled with bloody gunfire, graphic stabbings with knives and bayonets, and lots of gruesome explosions which separate limbs and leave blood everywhere. It has tons of guts, limbs, intestines, and tons of blood everywhere.
In the very first Hacksaw scene at Okinawa, one of the soldiers is shown with his legs blown off. Bloody strings of fat and muscle are shown protruding from his legs as he is dragged to safely. His femur and tibia bones are shown for several seconds
The kickstart of the very first Okinawa battle scene, one of the soldiers is slowly crawling through the war-torn battlefield. Suddenly, a wounded soldier rises from the rubble and starts screaming in terror in front of the soldier. A gunshot is heard and the screaming soldier takes a bullet to the back of the head, splattering brain matter all over the face of the soldier. Then they are both ripped apart with bullets. Very graphic, not for most viewers. Probably the most violent the movie gets
The main character is very close to a grenade explosion and is flung backwards. His legs and thighs are shown bloodied and burned. Not too intense. Not exactly a spoiler as this is briefly shown in the very beginning of the film
