About the spoiler: IIIRC, the ship's AI is stated as being able to control the battledress suits as though they were robots, to defend against the PC party. (There are no surviving troops when the ship is found.)3@Grav_Moped ... I am supremely skeptical that your spoiler notion would have even been possible.
For one thing, none of the second squad marines who would have trained and equipped with such armor have the opportunity to gain Engineering-1 skill ... which would be kind of necessary for routine maintenance (never mind annual overhauls at a shipyard). Furthermore, the experimental AI of the ship's computer was in the realm of security, not engineering, so the main computer wouldn't have been programmed with the necessary engineering skill on that side of things either.
Two NOPEs mean ... NOPE ... as far as I'm concerned.
So while it might be theoretically possible that your suggestion could have happened (somewhere, in a vacuum) ... the odds of it happening with the Kinunir given everything else revealed in the adventure (to the Referee, granted) put the odds beyond "you have got to be kidding me" in those circumstances.
Besides, can battledress armor even "work" without a (human) sophont wearing it?
I'm not just talking about "software issues" (log in, boot up, etc.), but also biomechanical issues (can it be operated remotely as an empty shell?).
I've always figured that battledress is more or less "high tech hardsuit" of the environmental enclosure exoskeleton kind, but that doesn't necessarily mean that it can "stand up on its own" and be marched around with no one inside of it via remote control. After all, if it COULD ... you'd have troops learning Communications skills instead of Battledress skills. Send in the "shells" while the "squishy people" remain hidden in a safe(r) location.
If the AI can figure out how to do either j-o-t or eng-1 (and with its own specs in the database and literal years of supercomputing time to work it out) it's at least possible.
