Where is great train robbery's rattlesnake chariot?

In the Battle of StarCraft II: Wings of Freedom, six rattlesnake chariots were hidden in the map of Astrotrain robbery checkpoint.

As shown in the figure:

The birth point of this pass is located in the highland in the center of the map, and the high-status mining site marked by the red circle in the upper left corner (guarded by a small number of enemies).

The blue circle in the above picture shows the position of six rattlesnake chariots, viewed clockwise from the main mine:

1, the first car is located on the left side of the main mine (at the same height as the main mine);

2. The second car is located on the right side of the ore separation place;

3. The third car is located at the upper right of the second car (the second car and the third car are on the same level as the ore separation plant);

4. The fourth car is located in an independent small highland above the main mine;

5. The fifth car is located in the independent highland at the lower right corner of the main mine (with a small number of enemy troops stationed);

6. The sixth vehicle is located in the lower left highland (there are also a few enemies stationed).

Precautions:

1. A team of marauders will refresh in the middle of this level. There are not enough rattlesnakes, so it is recommended to avoid them.

2. Although this pass is the entrance of the rattlesnake chariot, it is still a reliable combination of bunker+rifleman+tank under cruel difficulty; (provided that the siege engine has been obtained in the level)

3. The height of the first and sixth rattlesnakes is very suitable for a tank, because the enemy can't attack your tank if there is no air unit to provide vision. The only thing that needs attention is air defense. Watch out for enemy banshee fighters, raven bombs and machine guns, and protect your tanks.
