Follow-up Martial Manuevers

[Tech]

In a couple Martial Arts manuevers, as well as the Gymnastics Martial Arts in DH2, certain manuevers require that it follows a Martial Grab/Leg Grab. My questions are:

a) why isn't the manuever an automatic attack not requiring an attack role. The target has been grabbed and according to the Grab manuever, couldn't damage simply be done to the target?

b) can the follow-up Martial Manuever, such as Slam Flip occur in the same phase as Leg Grab (or Martial Grab) or would the special effect of the follow-up manuever suggest it be the next attack phase?

1. For the same reason that doing Squeezing damage in later Phases after Grabbing someone requires an Attack Roll -- it would be unbalancingly effective otherwise. You can rationalize it as the need to maintain a proper grip against a struggling foe or however you like, but the rule is that a separate Attack Roll is required.

2. The "Must Follow" attack occurs in the next Phase; it cannot occur in the same Phase as the base attack (UMA 93-94).
