The tank consists of two parts, the turret and the hull. To connect them into a tank, the turret must fall onto the hull from above; otherwise, the tank won’t form. If you want to assemble the tank, you need to enter it and press the HOME button, then unfold the separated parts using the wrench. Remember that if you want to dismantle the hull, it must have maximum health points; otherwise, you won’t be able to dismantle it.
