I'm confused lol. So you can see that cracked wall segment of the compound that looks like it should be rammed in but with what? I thought the semi truck but I cant get into it then I thought the APC but I blew it up... I'm honestly at a lost and been trying for like 20 minutes to get into some kind of vehicle.
If you're at the section I think you're describing there should be a waypoint to a vehicle that kind of looks like an APC/tank with rockets and a cannon. It'll tell you to hold X or whatever to get in, and then you blast through the cracked wall in front of you and drive through. You haven't got to Gould yet, right?
