I got it do it again. Here is what happened:
1. Vehicle backs down the road (AQUA).
2. Sturms are near (RED X).
3. Sturms try to get out of the way(BLUE X) of the p2 and 1 guy takes the yellow path. 2 guys take the green path. Leaving 1 guy by the P2 and 3 guys by the TP.
EDIT: I am dumb. It is just the wall. You can make the guys run all around that wall if you drive anywhere near them. Either side. Nice

The long walls need lots of holes added or I recommend just remove the map altogether. You have this giant wall of green cover and if something comes near your units they will suicide themselves running head first into the enemy.
