You think this cannon has only two tubes, but there are actually six tubes in the two tubes.It may not be very good at hitting moving targets, but hitting fixed targets can make fire coverage.I added a drone module to it for long-range artillery strikes.

Operation method:
Artillery:Use the left half for control.It can only adjust the pitch of the barrel, not the left and right.

Drone:Use the right half to start it.Use Activate Group 1 to eject.Pay attention to the little light at the end of the car, which indicates its direction, so that you don't disorientation

Some vulnerabilities:
The operation of UAV is not as simple as you think. If it is not well controlled, it will fly very high and it is difficult to see the ground.The two pairs of wheels in the middle do not know why they vibrate, which affects the accuracy of the gun to a certain extent.
