(Answered) Battle Armor jumping for 0 movement

[MoneyLovinOgre4Hire]

As Battle Armor do not track Attacker Movement Modifier, is it legal for them to expend jumping movement points while staying in the same hex in order to get the +1 Target Movement Modifier for jumping?  Provided that they would not be otherwise prohibited from jumping, of course.

This is addressed in the latest TW errata and the upcoming 10th printing, under Infantry Movement.  Basically, infantry can't jump and also remain in their same hex/level (unlike mechs).  If infantry is jumping, you're leaving your location.
