I f Reputation is to be believed the whitworth was certainly love at first site for the RWA. Based on the tables in Liberation of Terra 1 they had a serious hard on for the Wolverine, Shadow Hawk, Griffin and their home grown Phoenix.
for fighters the Vulcan, Ahab, and Eagle appear twice in the RAT for Heavies, Gotha, Lightning and Hellcat II for Mediums, and Zero for Lights (though the Cheetah Trident, and Tomahawk appear in the coveted 5, 6, and 7 slots for lights)
on the vehicle front the Puma, Fury and Rhino make up almost all of the RAT, with one slot for the Alachorn.
Until the Periphery Report comes out Liberation of Terra 1 is the best source for the RWA units.
