This idea was from a post I saw by Zorro (Super Jump Effect) I hope this works out.
Select one of the 10 trucks in the front stalls once your comfortable shot the metal wall this will start the truck.
You zoom zoom down an open field to a fortified base just as your about to crash the truck blows up. By prone jumping your body will launch at a high rate of speed (This does not work for the host but hopefully for other players.) Penetrate and gain access to the base.
