The invention discloses a tail supporting leg of a special operation vehicle. The tail supporting leg comprises a base, a supporting leg oil cylinder, a lower rotary arm, a turnover oil cylinder, an upper rotary arm, a rotary oil cylinder and a locking mechanism. One end of the upper rotary arm is rotationally connected to the tail of the frame, and the other end is rotationally connected with the lower rotary arm; the rotary oil cylinder is arranged between the frame and the upper rotary arm and is used for driving the upper rotary arm to horizontally rotate by 90 degrees; the turnover oil cylinder is arranged between the upper rotary arm and the lower rotary arm and is used for driving the lower rotary arm to rotate by 90 degrees to be folded below the upper rotary arm; the supporting leg oil cylinder is arranged in the lower rotary arm, and the extending end of the supporting leg oil cylinder is rotationally connected with the base; when the tail supporting leg is folded, the tail supporting leg is located in the longitudinal direction of the frame, and the upper rotary arm and the lower rotary arm are limited through a locking mechanism. When unfolded, the tail supporting legs are located in the transverse direction of the frame and supported below the ground level. The problem of setting operation in a narrow space can be solved.
