Batts (Was: Re: house rules/offline)

Somebody has probably said this already but what about the following:

AA Batts can fire through 1 arc. A Batts can fire through up to 2 arcs. B
Batts can fire through up to 3 arcs. C Batts can fire through up to 3 arcs and
can additionally target fighters using the More Thrust rules.

This gives a reason for all classes of batt.
