Now that we have a good look at what Tractor Beam does, it makes me want to try this build.

TOTAL = 100pts
The idea being to fly them in formation and do the long shots with the M3-A's to make the target more vulnerable and drag them into a more vulnerable position (out of Rang 3, into Range 1 or into more arcs) and the Kihraxz light them up. Additionally, since they're all PS2 it makes it easier for maneuvering, have free reign of my attack order and their higher PS ships have already shot making it safe to drag them into a closer range band.
NOTE: just because both M3-A's have Tractor Beams, doesn't mean they both have to use it that turn (might want to to drop the defence by 2, but that won't help against B-Wings or G-1A's), primary weapons are still an option.
