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.
