Rocketeers: The entire squad has Jump Packs and gains the Jump Back special rule.
Jump Back:You may roll a die at the start of any Assault phase to attempt to disengage from the enemy. On a roll of 1, you fail to Jump Back, and must fight as normal. On any other result you may move up to that many inches away from the enemy. You may not move into contact with another enemy unit.
pts: +30 seems to cheap, but if you make it to pricey than the unit won't be survivable enough to be worth the cost (+40 pts maybe?). Maybe give them Jet Packs instead, take away Jump Back, and restrict them from Heavy weapons?
