After re-reading Targets of Opportunity I was thinking about the Black Knight's rebuild specs.
Some basic things . . .
Miss Direction was BL9-KNT which fought on Tukayyid. Very clearly says it used a Vlar 300 XL to further it as a 9.
Mounts 2 ERPPCs, one 'extra' at the cost of some armor and both seem to be in the arms.
Mounts 4 Small Lasers, likely ERSL but maybe one was a SPL for anti-infantry work.
Still overheats unless properly managed.
Has medium lasers, at least two in the LA with a ERPPC.
No hatchet mentioned while other physical attacks are described in the book.
No mention is made of a Large or Large Pulse Laser in the book.
Based on ER/FM3145 we know the Knights' equipment would mount Clan weapons, something to give these elite troubleshooters an edge in combat. Holt supposedly hits a Hatchetman (model unknown) in both legs and nearly strips the armor- a IS ERPPC would only take half, but a Clan ERPPC would take two thirds.
Did we ever get any other specifics on her mech?
