Jump
If it does not Embark or Disembark from a Unit that activation, this Unit may Jump when it starts moving—during its move, but not at its end, it is an Aircraft with an X" Mv. If Embarking/Disembarking from a Zone, this Mv is not halved. If an AA Weapon Reaction Attacks it, this Unit suffers -3A for that attack. Line of Sight is measured to a point 2" above the Jumper. Jump Infantry are still damaged as Infantry.
