At last the attack has reache

d the Japanese mainland - Okinawa. First the assault on Wana Ridge, on which the Japanese Banzai Charge still has to continue to be the main character.
Step by step. Go up the ridge, receive the mission to eliminate the Japanese 3 200mm gun bunkers (to be honest, I never saw where the guns were during the attack), approach the bunkers, press 5 to take out the bombs, press right to throw them in, and detonate! After that, follow Sergeant Roebuck all the way forward, first clear the entrance to the Japanese bunker, and then kill the guards inside. Once you've cleared out the enemy, the mission is complete.
