From Periphery 1e, the Pleiades Hussars are a medium-heavy weight unit. So they will probably have lots of Warhammers, T-Bolts, Marauders, Archers and Griffins, all of which are built in the Concordat. According to the unit entry, in the years leading up to the 4th SW, they saw action against the FS conducting recon missions. So they may have salvaged Enforcers, Centurions, Dervish, Rifleman and Jagermechs.
As for armor, if you want a hover tank it is probably going to be the J. Edgar, which is produced at Perdition. Th only other vehicles produced by the TC at this time are all tracked, so you would have to just pick something from TR3039.
