They had a SL-era exosuit, the combat exosuit ( Mk. XXI ), the plans for an improved combat exosuit ( Royal (P)AL Mk. XXII ) but since they had no need to build them, as they had the origanal (P)AL Nighthawks. The origanal was kept in shape by all the little factories puttering out hand-built products. Same as the rest of the, I belive Royals myself, SL-era stuff.
Also, I belive they have at least a Bastion or two for system defence, but that is my thoughts. Wouldn't surprise me that they have a SDS grid as well...
