When Dr. Loveliss brings the tank out of the water to shoot McGrath's soldiers it moves into the midst of the soldiers and stops. The grass is cut into a bullseye shape. The tank stops just to the left of the exact middle of the bullseye. The action cuts to Loveliss and he talks and it cuts back to the same overhead shot of the soldiers and the tank and now the tank is right smack dab in the middle of the bullseye when it starts shooting.
