The AT-TE only spawns at the beginning of the game once the clone team has captured both A and B and if the AT-TE is destroyed the only way the clone team can get another is if the droids capture A and B then the clones take both control points back again which will cause a dropship to drop off another AT-TE tank at the clone spawn area.


The AT-TE really only has 4 directions it can be taken and it can help with 4 of the points.
There is a path off to the left that leads to A and E, 2 that leads to B and up the middle to C.


Starting with the path to A there is a cut through the foliage that leads to the landing pad.
Just follow the path that leads to A then go between the two gunships until your at E.



And once your past the landing pad are where the A is you can continue up the hill towards E.



There are 2 paths that lead over to B. Both of which allow you to help out at the B point.
But both directions are dead ends requiring you to turn around or back up all the way completely.


I do not recommend taking the AT-TE up the first path to B near the spawn since its impossible to turn around and so you have no choice but to reverse all the way back out until you all the way at the spawn again.



The second path to the B point is better as there is more room and it's easier to turn around.
It's still a dead end once you're at B but you don't need to worry about reversing.



These paths can be used by both teams to bring their tanks to support their teams.
Both teams tanks can use this back route to from from D to B or from B to D.
The gap near B can be passed through by both teams tanks.




There is 2 paths off to the left side of the Droid spawn that both lead to the D point.



Just press the front of your tank to the right side and then turn yourself left until you slip through.
