Weapons with HE value aiming at support weapons do have a chance of not only harming the crew but also destroying the support weapon with a single shot. Suppose the attacker manages to score a hit by rolling a number lower or equal to the HE value. In that case, the player may roll 2D6 to see if the support weapon has taken damage in addition to the effect roll on the weapon crew.
