1. First, we need to find the location of the military base with tanks. As shown in the picture below, the character drives the car to the location of the small red box.

2. Drive the car to the hillside next to the base and choose a vantage point overlooking the military base.

3. Take out a weapon (preferably a sniper rifle, aim far), aim at the military base, and look for tanks on patrol (it is best to go during the day, with good light and many tanks). Once you find a tank, attack it with your gun immediately.

.

4. After the tank is attacked, there will be 2 warning stars, and the tank will drive outside the base (be careful not to attack soldiers and police throughout the process).

5. After the tank drives outside, stop attacking and wait for the warning star to disappear.

After the police star disappeared, he immediately drove down the mountain to block the tank's way back to the base.

6. After getting off the vehicle, put away the weapon, approach the tank, carefully walk to the tank driver's position, press F to pull out the tank driver, and enter the tank yourself.

7. After the police star disappears, you can drive the tank on the road with arrogance.
