Part 22

Proceed down the path, using cover (press the cover button to crouch behind walls or objects), until you see the cave entrance. Eliminate the sandbagged Type 99 gunner beside the entrance and the stationed sniper on the ridge above.

Enter the cave and snipe the first stationed guard inside.

Past the first turn, eliminate the Type 99 gunner behind the overturned table. Be prepared for a 3-man patrol (armed with Type 100 SMGs) that patrols past this point. A grenade might be effective, or use cover and your heavy machinegunner and SMG-equipped squadmates.

Continue through the cave, past another Type 99 gunner, and clear out two more guards in a section with tables and jerry cans.

Proceed past another guard near a turn to the right. An offshoot to the right leads to a large room with two guards and a couple of TNT charges. Clear them out for rear protection.

Return to the first fork and take the left path. A right-way offshoot leads to the first cave entrance that needs to be destroyed. Take your demolition man down this tunnel, follow it to the end, and place the charge when prompted, then retreat.

Return to the main cave tunnel. Continue down the straightaway, which curves left, opening into a large cave. Defeat the two stationed guards here, collecting any goodies like a first aid kit, samurai sword, Type 97 grenades, and a Type 100 SMG.

Continue through the cave, which curves right then left, to a long straightaway guarded by an Arisaka guard. Snipe him and move forward.

Around the next curve to the left, an officer is stationed near boxes in a large cave opening. A sword-charger is out of sight past him. Defeat the officer, wait for the sword-charger to approach, then eliminate it. Collect the first-aid kit and grenades.

Continue behind the officer's position to the last cave opening. Go down the straightaway and watch for a sharp right turn. Snipe the patrolling guard in this section.

Continue past him to another jog, then an area where you can place a charge near the cave opening. Before placing the charge, eliminate the sandbagged Type 99 gunner outside the cave opening. Place the charge and run back to your squad.

After the charge explodes, you must fight your way back through the cave system, which has been reinforced with Type 100-toting enemies. Expect solo enemies, pairs, and groups, often stationed where you previously encountered guards. Notably, there is one enemy where the first cave opening tunnel turns off the main tunnel, and three enemies near the overturned table area (two stationed, one patrolling).
